A major difference between ABS and a human is that ABS controls braking force per wheel while human controls overall braking force. So when only one tire slips the ABS has advantage of around 20% more braking power. So I would say that unless we have a way to control braking force for each wheel independently (good luck with that) we're not going to beat ABS. I'm kind of curious how long would braking distance without ABS be while we don't care about traction, just smash the pedal and hope for the best.
One more thing I noticed - if this is a third gen Mazda MX5 (NC) it should come with EBD (electronic brakes distribution). I might be wrong but disabling ABS might be also disabling EBD which leads to too much braking force in the rear (no proportional valve to limit that as it was done electronically) which leads to rear wheels locking to easily at higher speeds. So in theory turning off ABS might set your brake balance as 50-50 (F-R) as default which is not great.
There was one test that I think might have been interesting alongside this, keeping ABS on but trying to break to the edge of it. Thus you only dip into ABS occasionally that in theory at least ought to smooth out the balance differences a bit and allow more use of the threshold, maybe. Surprised to see the ABS win so comprehensively.
threshold braking on with ABS on is outright faster than just slamming the brake and let ABS take over the braking. At least on motorcycle where you can individually adjust brake force of each wheel.
With the older systems, providing an apples to apples comparison, humans did in fact out perform ABS by a wide margin. But this is with expert drivers. That's the rub. Most people are average or subpar drivers and attention is lacking. Which means even with less effective braking of the older ABS, greater than average results were reasonably expected. Heck, people, especially women, still commonly incorrectly apply the brake peddle to allow the ABS to provide best results. ABS has only gotten better in the decades they've been around because of lower cost sensors and reduced manufacturing costs.
@@justanothercomment416 that's plenty interesting but how does that help him if his abs is broken? He's planning on trying to break the sucker right at the edge, clean off I'm assuming
Also this depends on the ABS system, we had a Dodge Durango that cycled the brakes like once a second. Definitely beatable. The abs on our Mini Clubman was so blistering fast I don't think any human could beat it.
Exactly the only way that this test would be fair is you completely removed the ABS system and converted the system to manual breaks with a proportioning valve
@@club6525 partial computer system ? In full manual brakes there isn't anything electronic a proportioning valve is just a simple mechanical device that allows proportionate front and rear bias which is necessary since there is only one pedal therefore you can't control bias fully manually
I thought it was interesting that it's a light car with a person in the driver's seat (right side for a UK market car) and he had trouble keeping the left tires (less weight) from locking up.

@MEGAPINT Knowing how to do something in theory and actually doing it in an emergency situation are two different things. Even professional race car drivers often lock up the brakes when trying to avoid another car that suddenly spun out in front of them.
Just to add to the mix, ~15 years ago I did the same thing with my BMW R1200GS motorcycle, equipped with ABS. Maybe the tech has improved, or is different for motorcycles, but I could consistently beat the stopping distance of the ABS manually modulating the brake levers (which is almost entirely front wheel braking under heavy load.) Only problem is, getting it wrong, in the heat of a critical moment (vs the low stress of testing) means washing out the front end and crashing. So, for me, ABS was still safer.
Motorcycle ABS has come very very far. Check out ProABS/cornering ABS from KTM: ruclips.net/video/hHRWg91hv-M/видео.html Compared to traditional ABS, cornering ABS keeps the bike from standing up and straightening out under heavy braking, and it also prevents you from locking the wheels and dumping the bike.
@@Jonathan_Doe_ "Motorbike ABS has only just started to reach a point where it’s decent" Bullshit. Bikes from around 2010 already had GREAT ABS. Newer ABS systems are better yes, but no way the old ones were less than decent.
I've always said this! In fact some years ago a friend asked me how to make his brakes better and I told him to fit some proper tyres (he used to fit remoulds!) and he was confused as according to him the tyres have nothing to do with the brakes 😂
When racing maybe, but on public roads and highways, having to both brake and swerve is unfortunately something that happens for a multitude of reasons.
I'm a litte experienced in the control unit calibration work in the car industry. From what I understand you not only loose ABS when pulling the fuse, you also loose the brake bias control. Modern cars are usually set up for a more or less 50:50 brake bias, since the rear can take quite much braking force, as long as the weight transfer has not "happend" yet. Therefore 50:50 brake bias on initial braking input and ABS handles the rest. If you pull the fuse, you end up without ABS (obviously) and a horrific brake bias. You can tell from Scotts attempt at 6:28 and 6:57, where the rear looses traction while the front is doing ok. Great job on that attempt, Scott! Probably not going to get much better...
My 2002 Priuses front brakes are fly-by-wire. If you pull the ABS fuse, you have very limited braking power, it's like driving a car with no power brakes.
for someone who is "experienced", you sure make a lot of incorrect statements. brakes ARE NOT 50/50 brake bias on most vehicles. thats EXTREMELY ignorant. it will depend on vehicle, but most vehicles' bias is set mechanically, not electrically. in some situations, you are correct. in others, you are not. it just depends. the rear loses traction due to weight transfer, how you do not understand that as someone who is "experienced"? talk less, listen more.
@@OxBlitzkriegxO You are absolutely correct on both your points. The bias is set mechanically, and the rear looses traction because of weight transfer. No denying on that. But since weight transfer does not happen instantly, there is a time at the very beginning of the braking phase, where the rear can take 50% brake force (assuming the weight distrebution of the vehicle is close to 50/50) without instantly locking up the rear. As soon as the weight shifts, the rear can't take it anymore (as you correctly said). That's the point where ABS kicks in and modulates brake pressure on the rear, virtually altering the bias. Most modern road cars are set up like that to maximise breaking performance (by utilizing the rear more at the start of the braking phase). Without the fuse this does not happen, therefore you "stay" at 50/50 and the rear starts to loose it. Well, most likely not exactly 50/50, but way more rear biased than, let's say, a properly set up non ABS vehicle.
@@OxBlitzkriegxO Most vehicles - you mean most older than 02/03. Almost anything newer is equipped with EBD (electronic brake distribution). The 3-channel ABS system (most advanced) treated both rear wheels as one due to technical limitation of proportioning valve being in the way. EBD is a step-up from that. It removes the need for proportioning valve as the brake bias is controlled electronically. This allows to exert more braking force in the rear due to initial brake distribution being 50:50 (this changes during braking to more conventional values), shortening the braking distance. The drawback is that with proportioning valve out of the system, when ABS and EBD turns off (they can't function separately) your stuck with 50:50 brake distribution whole time, so your much more likely to lock the rear. Mazda MX5 third gen (NC) used in the video comes with EBD from factory. Fun fact: torque vectoring, e-differential, ESC and a lot of TC systems require ABS and EBD to function (It's all basically one system but it's separated for marketing reasons).
The deactivated ABS system affecting the brake pedal ‘feel’ slightly may have had a very tiny role in this result. Servos also remove some feel from the pedal, it’d be interesting to see this test again with the car converted to a non assisted master cylinder with bias control setup. Older one or two channel ABS systems could easily be beaten by a trained driver threshold braking, 3 and 4 channel systems with independent solenoids for each front wheel, and one or separate solenoids for the rear… Very hard to beat. As these results show.
Nice thoughts; I think the non-ABS car would benefit, comparatively, from the comparison being two people (roughly equal weight) in the seats for the ABS and non-ABS tests. Seems like the pro driver was experiencing wheel lock up on the non-driver side different runs and the reduced weight on the wheels on that side was responsible from what I could tell.

@@alunesh12345 why are you commenting that here? Do you realize how counterproductive it is to randomly come into people's lives and force religion upon them? There's a time and place for that, and this time and place only makes a net negative force in the universe.
I don’t think a human could beat ABS, but if we had a 4 motor electric car we could probably run the normal brakes at like 90% and then control the last 10 ish % with the motors, since computer and electric components can reach the GHz speed unlike mechanical systems
there is an idea in some racing schools where your left without ABS for most of your schooling and introduce abs towards the end as a human with abs can outperform just full break force abs
jokes aside, good drivers should try this (in a safe and responsible manner!) to see what it's like and not be scared to rely on it if an emergency arises 😉
@@SpaceMissile ahh . Don't worry i will never do this in a unsafe location. I not the best driver ☺️ . I wanna be one . I wanna try this on a safe , empty ground . I wanna destroy my tyres
I live in Sweden and when we're taking our drivers license one of the onroad tests is the ABS. Obviously in a controled environment or a wide road with no other drivers around. And we also have a seperate tests which involves hasards such as aquaplaning, animals etc, and here we also test the ABS.
One thing I've ran into with ABS on, or at least the traction control systems. Is that when I am trying to slow down for a turn in icy conditions is that the traction control (controlled by ABS) likes to keep the vehicle going straight despite the direction I'm trying to turn. I've had a few times where I nearly ended up in the ditch because of that and ended up turning the traction control off to make those turns. Worth noting, with the system off, I could get the car to make the turns at the slow speed I was attempting.
To quote my vehicle dynamics prof: "Unless you can actuate 4 independent brake pedals 800 times per second to correct the braking force per wheel, you are worse than ABS"
Would be amazing to see the same test on a loose dirt road! The saying is that ABS performs poorly on loose surfaces, and I am wondering just how true that is.
abs will roll you into the bushes at 5 mph in the snow because it never locks all the way up to actually stop you. it slows and slows and slows and slows aaaaaaaaannnnnndddd wait a seconddddddddddddd okay youre stopped... you couldve stopped 4 feet sooner by just locking all fours at said 5 mph
@@bigbud4sure ive seen many an accident on youtube where a slide (typically off a highway following a fishtail) would be checkmate with abs simply because you cant lock the wheels up and continue sliding to a stop in a straight line. its a very rare situation so i get it, but its still completely unreasonable to me that i can physically avoid a crash but a computer wont let me
the only time ive ever crashed a car is with abs on dirt roads. absolutely horrible and will just chatter the wheels if the tiniest bit of slip happens
Lots of magazines have done this test. Results were wildly inconsistent, but did often win without abs. Problem is, you loose all steering control. ABS wasnt originally designed to stop you faster, its there so you maintain control of the car. Much more important 99%of the time.
I thought you'd get closer, and maybe beat it on ONE attempt, but you made an interesting point I hadn't thought of, ABS has control over each individual wheel, and I think that's going to be the big difference. Aside from the one time I freaked out the ABS on my BRZ at the track and got a flat spot, my already high trust in ABS is now even a little higher.
4 wheel abs requires huge power to rear brakes, more than you would actually need without abs. Another factor is the pedal feel and the master cylinder/booster setup. Only time taking the fuse out works is when stopping on ice and you still lose consistency every time
Now add some bumps and dirt on the road and enjoy 50-60 meters with ABS and still sub-40 without :) It would be a great system if it was allowed to overpush it and lock some wheels when needed. I drive for more than 15 years and still prefer to always disable ABS on my cars to always have predictible brakes and don't deal with glitchy computer in critical situations. The only exception is a race track as it's to expensive to buy new tires after a single wheel lock at the high speed :)
Overall, ABS is a great advancement. It is also worth considering that not all ABS functions the same across various models. Also, at least conventional ABS that I'm familiar can reduce braking effectiveness on loose surfaces like snow or gravel. Maybe there are some recent improvements, but I don't know.
I would expect that the loose surface tuning in modern cars with traction control is far superior to basic ABS in early cars that only had ABS, particularly with the move to compact SUVs over sedans - for all their faults compared to lower riding compact cars manufacturers are tuning them to handle low traction surfaces.
Thankyou for proving all the people who say ABS doesn't reduce braking distances wrong! I have always hated it when people say that as they are assuming that you never lock the wheels. Coefficient of friction is much lower than coefficient of adhesion, which is why locking the wheels increases distances. Imagine how much worse the human will be if you now keep changing road conditions with water, gravel, mud randomly added between tests.
No one says it doesn't reduce braking distances. We are saying humans CAN do better. And they regularly do. Look at the top GT3 drivers. If their cars use ABS, braking distances go up. Why? Because ABS REQUIRES the tire to lock up. Those drivers can ride the line so well that ABS activating does a worse job. ABS WILL catch lock ups faster than humans, which is why GT3s still use it. But it is still NOT the best way to brake for a skilled driver. The only time ABS does better than everyone is if the tires lock up. Then yes. ABS is better than all humans. But as far as only accounting for braking distances? Humans are capable of doing better.
Would be interesting to see time differences and consistency between using TC and no TC mainly on a wet surface, always wonder if its a strategically advantageous to use it on a slippy surface despite it feeling slow.
I would love to see this test repeated over different surface conditions (damp, wet, snow, ice) and different tire/brake setups per condition. I'd wager the stock ABS system is optimized for stock braking/tire components on dry pavement and would significantly struggle on say performance wet/dry tires on snow versus a competent driver.
@@skylined5534 I'd agree that damp/wet on stock suspension and tires the ABS most likely wins, but I honestly don't know what the effects would be with high-performance suspension tires on a stock ABS module. I've empirically (anecdotally) validated on several cars I've driven that I can stop quicker on compact snow/ice. That being said, I think it would also be neat to test a timeline of ABS systems (although that would be much more difficult to control for i.e. how do you put a 2023 ABS system in a 2001 Miata or a 2001 system in a 2023 Miata?).
I think I saw a similar video many years ago on a honda CBR, where a professional rider could not get close to the ABS. The fact that you can MASH the brake and get a better result in any situation than nearly any human is also the reason they made it mandatory on cars.
I'd have cut the first two results from Scott. He just had to discover how this is done. And I'm surprised how close he could get to the numbers with ABS on at the end. Thanks for another nice test! And I'd like to second the proposal from Paul Keeble. Is a race driver (Scott) able to stop faster, if he tries to brake at the edge of triggering the ABS, without turning it of?
I think that leaving those in is part of the point of the video. He has years of racing experience and it still took him a couple of tries to get close.
like they said, in real life you don't get to sail straight through the kid who stepped into the road, say "oops! sorry!! I didn't quite estimate the required brake force correctly that time" and have another go, road conditions, tyre condition, tyre and brake temps change all the time, you're always going to either get it wrong the first time or be lucky to get it right the first time, meanwhile with modern ABS systems you'll pretty much always get 90%+ of what the brakes are capable of at any given moment.
@@RWoody1995 yeah youre right. you could outperform an abs but then you need conditions that arent given in rl circumstances. humans are imo always capable of outperforming car electronics but are mostly never capable to do it when its needed. but also im for learning to drive without such assistance, like learning to brake if the system is failing. i learned driving a bike without abs. i often wish i would have got one but i dont want to relie on such a system. nice to have but mandatory to be able without! thats why i trained braking on the bike. if you relie on assistance you shouldnt have a license because you are lost without it. sadly driving schools are to modern and if something fails YOU WILL fail. so sad..... and thats in germany where laws get out of hand. and every fuckin car should have so much assistance that you shouldnt even have to do more then steering. relieing on a machine is imo more insane then driving without by far. i also tried drifting in the snow on the bike and i learned a lot about saving my bike if the front starts slipping and how to "power"drift. okay 125c c15hp and such a rough idle that 100% throttle at idle meant that the wheel broke lose even though the power wasnt enough at 15hp if i used the gas softly. very interessting experience!. think about it , half the torque and by far less power and the kick was enough to lose traction while full power and torque wasnt enough if delivered smoothly. ever had such an experience? i mena kinda logic. if you drop your clutch hard they tires just get ripped of "before they can grip" the surface (even though that this is scientific wrong because of the torque spike not the missing gripping because it always has traction at some degree)
I generally advocate for abs and traction control for regular cars… but I’m really surprised neither could beat ABS with that many tries. I didn’t consider the electronic brake force distribution though and guaranteed that will make it impossible to beat.

Abs yes, 100%. But traction control is just dangerous imo. ive had (on mazdas) several situations where mid corner the tc kicks in and tried to put me in a ditch. When i was no where near breaking traction. Its like halfway through a corner the car just attempts to straighten itself out by braking individual wheels while the steering is still pointed where i want to go. Its extremely unnerrving and imo, downright dangerous.
Another thing to consider is that modern ABS also controls the brake bias, in our RX8 race car is you disable abs it will put the braking bias to almost 100 front as it thinks something is really wrong with the system and you will destroy your tires as you understeer off your line. My 1988 RX7 FC doesn't care at all if you pull the ABS fuse and will function as normal minus you being able to lock up the wheels at extreme braking. I would not be surprised if your Miata did the same thing, it being modern.
There is one test i would like to see. The same test on gravel (or snow), which atleast in the 80's/90's was claimed to be better without ABS. Albeit the abs then was worse than now. The same was said for snow. (that was the reason audiclaimed for having a ABS shut of button in the dash at the time)
for sure in the snow condition you can beat the ABS, with experience I barely engage ABS anymore... It's icy well just need less brake a longer distance. I did the test on my way to work one day and if a floor the pedal for maximum force it just pulse and barely slow the car to the point of blowing a stop sign but the car was still straight. on the other hand, if I brake until the ABS pulse and come back a little to avoid it kick in, it slow a lot better to the point it the seatbelt that retain me in. I did it on winter tire more wider (235 instead of 215 with the most wider contact patch for that size) and I'm in Canada... Also the sound the snow make during braking is important to know the grip, if it slip the sound goes away(or you are stopped) but when you brake the snow crunching noise goes higher and higher until it slip. The snow on the ground make a little mountain in front of a tire during braking
ABS developer here. Well, on deep gravel or snow, locked wheels can in some scenarios dig in and collect a wedge of gravel in front of the wheel, which may stop you very quickly indeed. One downside is that if you happen to have gravel only on one side of the car, the resulting one-sided gravel wedge will spin your car sideways, digging the now forward facing side wheels into the gravel and flipping the car over. Also, modern ABS on offroad cars can be set (manually or automatically depending on manufacturer) to some offroad ABS setting that then tries to build a wedge, then roll over it, build another one and so on. Beating ABS may still occur when offroading a car that was not made for it, but then you will have bigger problems.
Thing is, even if a human _could_ beat ABS some of the time, it is the consistency that is the issue. You might be able to do it well when practicing, but could you still do it in a panic stop situation? It has to be instinctual, and that take a ton of practice, if its even possible at all, as I've seen plenty a race car driver lock the brakes and not pump them before collision.
Much better than the older video. But still flawed. The MX5 brakes are designed with the ABS in mind. So who knows what the front/rear bias is. Bypass all the electronics, add an adjustable proportioning valve, give the drivers a car that can be designed to work without ABS. Even with a poorly adjusted system, an average driver with no experience driving non-ABS cars was able to get within 5m of the ABS baseline. I bet a properly designed system would let the pro get within striking range of the ABS.
You shouldn't compare ABS-enabled car to ABS-disabled, but to non-ABS car with mechanical brake distributor instead. Removing ABS fuse makes your car brake worse than non-ABS car because of absolute absence of brake distribution. Brake distributor installed in the rear end and connected to rear suspension will adjust rear axle braking force according to suspension position - the more car leans forward, the less brake force is applied. Being set correctly this system allows to brake much better than ABS, though you need to get used to it on specific surface each time.
We also have to remember that ABS has been refined for a long time now - early ABS were a bit crude and can probably be beaten, but any vaguely modern system is realistically unbeatable.
Much better video than your last one. I'm also surprised to see by how much you couldn't beat the ABS - I've been in situations where an unwanted ABS intervention genuinely seemed to reduce the braking force. As others have posted, this isn't necessarily a direct with/without comparison as ABS-equipped cars generally have a greater rear brake bias, and heavily-servo'd modern brakes make threshold braking more difficult. An interesting further comparison might be a car that was available from the factory both with and without ABS - The MK1 MX-5, perhaps? Although a thirty year old car probably isn't a great example of the state of modern ABS technology!
this test is flawed because youre attempting to use a system thats designed for use with ABS, without it. it is not designed for that situation and thus, is incorrectly biased. im certain that installing a proportioning valve or two would change the results of this test. he managed to get very close to the abs distance with a flawed system for manual braking. i dont remember who it was but many years ago, there was a F1 driver who easily managed to out brake an abs equipped car.
Intresting. but a proportioning valve can be used with an abs and enhance braking even more. so again you do not compare the same things. as far as the f1 driver, if it was over a decade ago, the abs technology was far less advanced and could not handle each tire seperately. with today technology, there is no way to beat abs consistently in scenarios like this(emergency braking on a straight line). The abs does not lock and unlock the wheel at short random times. It consistently keeps each tire at max grip, that can offer up to 20% more efficient braking power than if you could handle perfectly 4 wheels at the same time. Streetwise, it can't get better. In track is a whole other discussion.
Also worth noting that this is a known braking point, you can anticipate it. Whereas ABS is even better for the times when you didn't - or couldn't - anticipate the need to brake aggressively. Even if someone got close on-track doesn't mean they'd get close on eg. drive home in dark in the rain after a long day
As a simcade player I'd say I can (with certain cars though, and I still leave ABS on because consistency), the main point to turn it off is when you don't have to go to zero but want to have best steering control when braking
I have done the same test and my results were very different. My pedal action is different. I come to threshold and back off ever so slightly, and then increase pressure slightly as I come to a stop. These results were consistent with in the vehicle driven. Most cars I was quicker.
@@egullSZ Not me. Maybe the driver in this vid. I use the e-brake and pedal modulation to stop the shortest. Another trick with the e brake is when going over big bumps you can put some tension on the rear springs as you over to smooth the transition. This allows you to go over things way faster without catching air.
To be fair, I think it is way harder to brake with a car that has a braking system, which is optimized for ABS and has ABS turned off, than with a car that does not have ABS at all. It is way harder to modulate the pedal imo. So to me it seems like this is an unfair comparison for non-ABS-braking.
ABS is not to achieve maximum braking performance. ABS is to locking the tires from breaking traction, skidding, due to issues with the driving surface. In optimal conditions, a trained driver WILL outbreak ABS. However, regular folks usually won't, and in wet, snowy, or icy conditions, in conditions of uneven surface or unimproved roads, or when attempting to brake and maneuver at the same time, ABS will outperform a person.
I tried this test from 100kmph in my nonABS 1984 Mitsubishi hatchback and got 27 metres on my first run and 29 and 30 metres on 2nd and third attempt. Not bad for 40+ year old car with only a drum to disk rear conversion.
Is there anyone monitoring the entry speed and when braking occurs? Looks like the non-abs runs starts braking a lot earlier than the cones. Also a small difference in entry speed makes a big difference in stopping distance. Energy is proportional to velocity squared so a small difference in entry speed is not negligible.
then there is racing ABS which allows to trim it depending on grip. another thing, some guys claim better braking in an abs car by modulating the pressure right at the limit where the ABS doesn’t kick in and lets the wheel free a little bit
Are the rear brakes more effective with ABS? Street cars have brake balance towards front, so without ABS the front brakes lock while the rear brakes are not biting yet?
You guys should try this in the snow as it will take more time for the wheel to unlock and because abs is so aggressive you could probably beat it by a lot…
During driving ed we we're on a slippery course and compared braking with and without ABS. We turned the car off to achieve braking without ABS and we did not let off the brakes when decelerating. Without ABS resulted in a shorter braking distance, but the car also did a 180 doing it so not ideal to do in traffic.
Since you have only one pedal for 4 tires / breaks you have to tune the break biases perfectly to beat ABS which can control the breaks on each tire individually.
One thing to consider is that race cars with no ABS have much shorter travel brake pedal. It’s easier to modulate the pressure in MM rather than 10 CM for a road car. But for a road car not suitable as they require a lot more leg power
This car is designed to have ABS, there is no brake proportioning valve and may tend to lock rear wheels. In most non ABS cars you have some sort of BPV, either constant pressure, or variable one based on rear axle load to avoid going sideways.
You should done a comparison in the end with abs on, just to see how much the wheels been degraded from all those lockups, probably would have been wors then the first abs test
A 5m average behind abs.. I'll stick with my all hydraulic non electronic , manually adjustable bias brakes. Like the guy said abs can only help when trouble happens. A human can predict conditions and prepare. Abs can not. Abs just makes drivers reckless because they never Learn the limits of their machines and just expect the abs to do all the work.
That was a great test and actually amazing how much technology can aid in making vehicles safter. Thought pros might beat the ABS during braking when I saw the title and was curious, turns out they don't.
@@mica410 ABS is usually tuned to attain a specific slip ratio on the tyres which is determined for the stock tyres usually; but this value changes as the tyre wears. Turns our ABS wins still.
Have you replaced the tires between runs? Because flatspotting can seriously hamper breaking performance, and the first guy flatspotted all 4 tires for certain.
Forgive me for my ignorance, but if we aren't worried about controlling the car under breaking and we'are strickly worried about the stopping distance, shouldnt you just go for a full skid? Wouldn't just slaming on the breaks and the the tires going full lock actually help with stoping distance? Or was the test also including control under breaking? Please someone correct me on this.
i did this test 10 years ago and i handily beat abs. surface had less grip though. now on mud... abs will just try to kill you every chance it gets by taking ALL braking away from you
I think another variable for the ABS being on the car or not how sticky the tires are. If you're in a race car that has racing tires that are more sticky and give you more grip you're less likely to lock up at the limit if those tires can scrub your speed fast enough. Considering most street tires are pretty junk when it comes to heavy braking anyway
Actually, I have a Polo 6R with ABS on, and when I put pressure on the brake pedal just barely before the ABS starts to work, I feel more deceleration than with ABS, the pressure must be accurate otherwise the ABS will work or you will lose break power if you don't push enough, adding to that the temperature is always changing and the road rugosity too, also most people will brake hard when a dangerous situation occurs and by reflex everyone will rely on ABS in that situation.
Disabling ABS also disables brake force corrector... So for proper test u should use car w/o ABS from the factory and similar model with ABS equiped (cars back in time had ABS as option).
i'm not surprised about this. abs is just awesome and every car should have it, even performance- and fun track day cars. it doesn't spoil the fun, it just adds something you can't accomplish yourself anyway
Interestingly they demonstrate this at the Porsche experience, and the best braking comes from having ABS but modulating the pressure slightly when it kicks in - combination of ABS and driver skill (not just mashing the brake pedal) wins out. I notice the Mazda is locking its rear wheels, which is not a good thing on a road car, probably from lightening the car - needs a brake bias adjustment then it might stop sooner.
As other comments stated. This car was engineered for ABS. Cars engineered as non-ABS have much more pedal feedback and have a better setup brake bias and brake balance. A car with ABS doesn't mechanically limit the force to improve brake bias, rear brakes and front brakes will be setup for maximum force and let the ABS manage the rest. This test is still very scientifically sound. I'm just saying that a car with no ABS from factory is totally different from a car with ABS "turned off". But and interesting test would be a car from the 80s/90s where the ABS was an option. So the car was engineered for no ABS but had it has an option or a trim.
If you had individual control over the front and rear brakes like on a motorcycle, I think you’d be able to stop a bit quicker. The problem is that cars tend to be built for convenience. But emergencies aren’t convenient, are they?
I don't think anyone can beat ABS with a fixed brake bias: without ABS braking systems are optimized to lock front and rear axle at a high deceleration (usually around 1g) and with the front axle locking first because it is safer (as we saw in the video, when the rear locked first he had to a huge correction on the steering), staying as close to this point will grant the maximum performance, but it is still with a fixed ratio between front and rear. With ABS on and the front wheels would lock, it will prevent not doing it so the wheels can apply the maximum braking force to the ground, but the rear wheels can still increase their braking force till the point they would lock too. This will grant a higher deceleration that is not achievable without ABS, since the locking of an axle cause a drop of the force that it can apply on the ground.
A good test, but the only issue is the driver is not always going to start braking at the same spot each time. You need something like the old style chalk gun to indicate where the brakes were first applied. Will's third test looks like he started braking well before the cones. At 3:40 the front of the car is dipping and braking starts very shortly after.
Can a Human BEAT ABS? yes, but not reliably or on command or in most cases. there's a reason it's considered a performance enhancer in racing. however perfectly controlled consistent braking force IS superior to pulsed actuation, we just don't really have a technology for that yet.
I have a feeling it varies depending on how old and crude the ABS system is, and perhaps tyres? The only reason I say that, is that in my autocross car (an early 90s Mazda 323F) I had a problem where once I put semi slicks on it, the ABS seemed to really have a bad time with things, and reduce brake force too much, unplugging the ABS fuse made it much easier to make a hard stop in the gate at the end of an Autocross run, seemingly to the tune of like 3m or so shorter...
Just wanted to say I keep seeing this video and every time I really wanna press it because of the thumbnail but I'm just not interested in the topic. So just wanted to inform you that the thumbnail is REALLY good in my opinion even though it may not get as many views.
Id say in the winter on snow/ice...ABS off can be better. if the ABS is too sensitive or the road is too slipery, the car just wont slow down at all. The ABS just keeps releasing the brakes But thats a car to car basis, not a blanket statement
The driver does not have the same access to the braking system as the ABS unit has. So even if a human was faster and better than a computer, they simply wouldnt be able to make use of it. Its about the same as with traction control or ESP. The driver does not have the hardware to tune the amount of torque going to each driven wheel individually, he only has 1 throttle and 1 brake and maybe 1 clutch pedal. You relatively often hear people say that racecars dont really have any electronic driver aides, so its just a skill question. No. (Some) Racecars dont have ABS because theyve got absurd amounts of grip. Plus, the drivers are constantly working at the limit of their vehicles, the last thing they want to happen is for the electronics to suddenly cut power or apply the brakes on a wheel mid corner.
IF (big IF) I could turn off the ABS on my truck, I could stop it probably 30 feet SHORTER without the ABS than with it. I removed the ABS from my 1994 Suzuki motorcycle just for that reason and to remove the 30-odd pounds of weight that it entailed. I did a "Smash-thru test" on the Suzuki. I test stopped the bike as fast as possible WITH the ABS and set-up a paper barrier at the EXACT point on the track where I had stopped. Then I removed the ABS from the bike and stopped it as fast as possible without the ABS and measured my distance from the sheet of paper- about 12 meters, then I moved the BRAKING POINT MARKER 13 METERS FORWARD to see if I could STOP before HITTING the PAPER BARRIER with HOT TIRES AND BRAKES. I did 15 times with the rear tire in the air every time on video about 250 mm! (A "stoppie"). I never touched the rear brake at all. I'm VERY good at braking on a bike or in a car or truck.
Iinteresting video.A few years ago I went on a skid pan, old Granada soaking wet, and bald tyres to make sure it skidded. It had switchable abs and they taught us cadence braking which always worked better than the abs. Does that mean abs is less effective with really low grip or maybe a more modern abs just works better?
if on dirt roads, you must turn off all assist, ABS will not allow the tires to dig in the ground and push material to pile infront. TC will constantly cut power to wheels that actually need it and upset balance, specially in a sand trap situations. saw a 2016 dodge ram at the beach once burning through its transmission because TC block power, a flat bed had to pull it out.
Apparently ABS is bad on slippery surfaces such as snow and ice and probably dirt because even light braking will cause your tyres to slip, and ABS will reduce the braking trying to get grip so much that there's barely any braking at all.
Thank you for revisiting this test. That said, I wonder what else was disabled when you pulled the ABS fuse? And what is the hydraulic brake bias? If the ABS is designed to compensate for a less-than-optimal hydraulic brake bias, you may be setting yourself up for failure.
Believe in JESUS today, confess and repent of your sins. No one goes to heaven for doing good but by believing in JESUS who died for our sins. For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.(John 3:16)🥳❤️
idgaf abt stopping fast at the end of the day if i cant lock up my brakes i cant hook my nose down thru the corner and oversteer into the apex making me slower
Does the car have steel or carbon ceramic brakes because the stopping distances from that speed can be impacted by about 10 meters if there are steel brakes.
I am surprised too. I thought Scott would be much closer to ABS, if not better. I'd be interested to see how that experiment translates to a track lap time though, rather than straight line braking. Does ABS help lap times, or can drivers do better without? I may have to revise my mis-conceptions...
ABS shortens braking distances so even in a straight line, on a track, it has a huge advantage, being able to brake later. You can also keep braking during turn-in, and although threshold braking is probably the way to go if you're a seasoned driver, the casual trackday enthusiast does nothing but benefit from ABS.
Watching RUclips adverts combined with Brilliant adverts really slices up the watching experience. I really miss the days it was only RUclips that shafted you with ads. Now we get shafted from both ends.... And not in a kinky way :(
So if you train yourself to do this with your car, and you get exceptionally good at it. You are almost comparable to abs-braking. Unless it's a super stressful situation where you forget all you learned. An old timer said that modern cars with techonology is rubbish, but even he admitted that ABS, traction control and airbags were a life saver. The rest is just uneccessary trinkets. Even so, if you drive very old cars it is worthwhile learning how to brake properly just to increase your odds of surviving.
I would retry this on a older car as newer car use the abs computer and pump to manage brake bias, so you get inconsistencies in braking performance with abs. Also stock pads do not give enough modulation and feel for me.
In cars it makes sense to have ABS. The computer can control each wheel individually while you cannot. On motorbikes however you can, and I've found that on most bikes the ABS setting is a bit too conservative, and you usually can't turn it off except for higher spec models. On a bike your primary front brake is used with your hand, so you can modulate a lot better. It's kust anecdotal but personally I'm more annoyed with ABS on motorcycles.
the main purpose of ABS is not about shorter break, but a controllable, consistant and less dependent on surface. on ice you probably can beat ABS in straight-line braking, but you will lose control 9 out of 10 times. when you not locking up (and that's what ABS doing), you can control and steer, and it can save others life, property and your car.
I think you should do the test but with a british trained Advanced driver ( by British i mean the UK advanced driving course and training). By the looks of it, none of the drivers used cadence braking which is like ABS but for a human input rather than a computer doing the work.
Should have put the fuse back in at the end to see how much tyres and brakes were affected. Also it would be good to have a data logger onboard to see what the actual numbers are because it looks like the front dips sooner when doing most of the abs runs. It should also be noted that this will be dependant on surface, traction available and most importantly the abs system itself. Some of the early systems were atrocious and easy to beat. On the other hand some of the new stuff would make that system look like it wasn't trying. Electronics have come a very long way since the 90's.
Other comments have mostly said it, but 4 channel ABS/ESC systems (where two isolated hydraulic systems are separated diagonally, not front to rear) are designed specifically to work only with the control system functioning to adjust bias. Without the system functioning you typically end up with a catastrophic rear brake bias. This video proves pulling the fuse on 4 channel diagonal hydraulic brake system is not good. A proper test would be a car offered with ABS optional vs not optioned, NA Miatas would be good for this, although most early ABS systems are probably 3 channel, treating the rear wheels as one input and potentially retaining a front/rear proportioning valve that would feel more natural even with the system not functioning.
This doesn't even demonstrate the biggest benefit with ABS (although you did mention it) . The car is still steerable no matter how hard you brake, while if the wheels lock up you can't steer. An inexperienced driver or even an expert driver might forget to ease of the brake when needing to avoid a sudden obstacle. Leading to the car losing traction and continuing straight ahead. This is something we learn and get to try ourselves while getting our licence in Northern Europe along with driving on ice.
If you have to go on a Police driver re-education course you will discover that the official line is that ABS does not alter the stopping distance at all, but merely allows you to steer and maintain control under braking. This is the official line and they allow no argument. Just as they argue that those stopping distances in the Highway code are still valid and accurate after 75 years.
Short Answer: If you focus, maybe you can brake close to ABS. But no matter how professional you are in traffic, there is always the possibility of panicking and pressing the brakes all the way.
A major difference between ABS and a human is that ABS controls braking force per wheel while human controls overall braking force. So when only one tire slips the ABS has advantage of around 20% more braking power. So I would say that unless we have a way to control braking force for each wheel independently (good luck with that) we're not going to beat ABS. I'm kind of curious how long would braking distance without ABS be while we don't care about traction, just smash the pedal and hope for the best.
They have a previous video on this topic, and that's exactly what they compared
@@DeltaInsanity Thanks I found it.
One more thing I noticed - if this is a third gen Mazda MX5 (NC) it should come with EBD (electronic brakes distribution). I might be wrong but disabling ABS might be also disabling EBD which leads to too much braking force in the rear (no proportional valve to limit that as it was done electronically) which leads to rear wheels locking to easily at higher speeds. So in theory turning off ABS might set your brake balance as 50-50 (F-R) as default which is not great.
Yeah just 4 more pedals. No biggie
@@Doktoreq I prefer the 31-69 distribution, nice
There was one test that I think might have been interesting alongside this, keeping ABS on but trying to break to the edge of it. Thus you only dip into ABS occasionally that in theory at least ought to smooth out the balance differences a bit and allow more use of the threshold, maybe. Surprised to see the ABS win so comprehensively.
How would you dip into ABS occasionally if you break it? Lol
threshold braking on with ABS on is outright faster than just slamming the brake and let ABS take over the braking.
At least on motorcycle where you can individually adjust brake force of each wheel.
With the older systems, providing an apples to apples comparison, humans did in fact out perform ABS by a wide margin. But this is with expert drivers. That's the rub. Most people are average or subpar drivers and attention is lacking. Which means even with less effective braking of the older ABS, greater than average results were reasonably expected. Heck, people, especially women, still commonly incorrectly apply the brake peddle to allow the ABS to provide best results.
ABS has only gotten better in the decades they've been around because of lower cost sensors and reduced manufacturing costs.
@@justanothercomment416 that's plenty interesting but how does that help him if his abs is broken? He's planning on trying to break the sucker right at the edge, clean off I'm assuming
Also this depends on the ABS system, we had a Dodge Durango that cycled the brakes like once a second. Definitely beatable. The abs on our Mini Clubman was so blistering fast I don't think any human could beat it.
by pulling the ABS fuse, you also deactivate the ABD which controls the break bias between the wheels...so you have even worse breaking
Exactly the only way that this test would be fair is you completely removed the ABS system and converted the system to manual breaks with a proportioning valve
Doesn’t matter keeps it exciting to drive
I also drive with a broken balance bar in front in rain or snow my front snaps 😂
@@Thanos.m That wouldn't be fair. You're relying on partial computer system which is similar to ABS
@@club6525 partial computer system ? In full manual brakes there isn't anything electronic a proportioning valve is just a simple mechanical device that allows proportionate front and rear bias which is necessary since there is only one pedal therefore you can't control bias fully manually
I think the main advantage of ABS is it can go on each individual wheel instead of having to work with the weakest link
I thought it was interesting that it's a light car with a person in the driver's seat (right side for a UK market car) and he had trouble keeping the left tires (less weight) from locking up.

@MEGAPINT Knowing how to do something in theory and actually doing it in an emergency situation are two different things. Even professional race car drivers often lock up the brakes when trying to avoid another car that suddenly spun out in front of them.
@@alunesh12345
Screw your control method.
Just to add to the mix, ~15 years ago I did the same thing with my BMW R1200GS motorcycle, equipped with ABS. Maybe the tech has improved, or is different for motorcycles, but I could consistently beat the stopping distance of the ABS manually modulating the brake levers (which is almost entirely front wheel braking under heavy load.) Only problem is, getting it wrong, in the heat of a critical moment (vs the low stress of testing) means washing out the front end and crashing. So, for me, ABS was still safer.
Motorcycle ABS has come very very far. Check out ProABS/cornering ABS from KTM: ruclips.net/video/hHRWg91hv-M/видео.html
Compared to traditional ABS, cornering ABS keeps the bike from standing up and straightening out under heavy braking, and it also prevents you from locking the wheels and dumping the bike.
Motorbike ABS has only just started to reach a point where it’s decent, the Bosch cornering ABS systems Ducati Ktm and others use now are amazing.
@@Jonathan_Doe_ "Motorbike ABS has only just started to reach a point where it’s decent" Bullshit. Bikes from around 2010 already had GREAT ABS. Newer ABS systems are better yes, but no way the old ones were less than decent.
@@mrfatmanjunior bruh I’m so old when I say recently that basically includes from 2000 onwards 😂😂
@@Jonathan_Doe_ ABS was super, super rare in the 2000's. Trust me even the old ABS systems are better than no ABS.
The most important upgrade you can do to your brake system is tires. If abs kicks in easily you don't need better brakes, you need more traction.
I've always said this!
In fact some years ago a friend asked me how to make his brakes better and I told him to fit some proper tyres (he used to fit remoulds!) and he was confused as according to him the tyres have nothing to do with the brakes 😂
EXACTLY!!!! the limits of basically every force on a car is on the tyres, even if you got ABS without a good set of tyres you will probably crash
...or the brake bias is off.
@@skylined5534 I've been laughed to scorn for telling people that brakes don't stop the car, the tires stop the car...
And that was in a straight line. Imagine needing to brake hard AND needing to turn to change la e for example
If you find yourself needing to brake and turn at the same time, then you already fucked up.
@@colehartel7206 That's why ABS exists tho. Humans fuck up.
There should never be a time where you have to use both your steering wheel and the break pedal at the same time
When racing maybe, but on public roads and highways, having to both brake and swerve is unfortunately something that happens for a multitude of reasons.
@@stonksmcmeme & @droussel are on point, ABS is far superior in emergencies because of steerability.
I'm a litte experienced in the control unit calibration work in the car industry. From what I understand you not only loose ABS when pulling the fuse, you also loose the brake bias control. Modern cars are usually set up for a more or less 50:50 brake bias, since the rear can take quite much braking force, as long as the weight transfer has not "happend" yet. Therefore 50:50 brake bias on initial braking input and ABS handles the rest.
If you pull the fuse, you end up without ABS (obviously) and a horrific brake bias.
You can tell from Scotts attempt at 6:28 and 6:57, where the rear looses traction while the front is doing ok. Great job on that attempt, Scott! Probably not going to get much better...
My 2002 Priuses front brakes are fly-by-wire. If you pull the ABS fuse, you have very limited braking power, it's like driving a car with no power brakes.
for someone who is "experienced", you sure make a lot of incorrect statements.
brakes ARE NOT 50/50 brake bias on most vehicles. thats EXTREMELY ignorant.
it will depend on vehicle, but most vehicles' bias is set mechanically, not electrically. in some situations, you are correct. in others, you are not. it just depends.
the rear loses traction due to weight transfer, how you do not understand that as someone who is "experienced"?
talk less, listen more.
@@OxBlitzkriegxO You are absolutely correct on both your points. The bias is set mechanically, and the rear looses traction because of weight transfer. No denying on that.
But since weight transfer does not happen instantly, there is a time at the very beginning of the braking phase, where the rear can take 50% brake force (assuming the weight distrebution of the vehicle is close to 50/50) without instantly locking up the rear.
As soon as the weight shifts, the rear can't take it anymore (as you correctly said). That's the point where ABS kicks in and modulates brake pressure on the rear, virtually altering the bias.
Most modern road cars are set up like that to maximise breaking performance (by utilizing the rear more at the start of the braking phase).
Without the fuse this does not happen, therefore you "stay" at 50/50 and the rear starts to loose it. Well, most likely not exactly 50/50, but way more rear biased than, let's say, a properly set up non ABS vehicle.
@@OxBlitzkriegxO Most vehicles - you mean most older than 02/03. Almost anything newer is equipped with EBD (electronic brake distribution). The 3-channel ABS system (most advanced) treated both rear wheels as one due to technical limitation of proportioning valve being in the way. EBD is a step-up from that. It removes the need for proportioning valve as the brake bias is controlled electronically. This allows to exert more braking force in the rear due to initial brake distribution being 50:50 (this changes during braking to more conventional values), shortening the braking distance. The drawback is that with proportioning valve out of the system, when ABS and EBD turns off (they can't function separately) your stuck with 50:50 brake distribution whole time, so your much more likely to lock the rear.
Mazda MX5 third gen (NC) used in the video comes with EBD from factory.
Fun fact: torque vectoring, e-differential, ESC and a lot of TC systems require ABS and EBD to function (It's all basically one system but it's separated for marketing reasons).
Did you miss the part where he mentioned this in the video?
The deactivated ABS system affecting the brake pedal ‘feel’ slightly may have had a very tiny role in this result. Servos also remove some feel from the pedal, it’d be interesting to see this test again with the car converted to a non assisted master cylinder with bias control setup.
Older one or two channel ABS systems could easily be beaten by a trained driver threshold braking, 3 and 4 channel systems with independent solenoids for each front wheel, and one or separate solenoids for the rear… Very hard to beat. As these results show.
Nice thoughts; I think the non-ABS car would benefit, comparatively, from the comparison being two people (roughly equal weight) in the seats for the ABS and non-ABS tests. Seems like the pro driver was experiencing wheel lock up on the non-driver side different runs and the reduced weight on the wheels on that side was responsible from what I could tell.

I don’t think a human could beat ABS, but if we had a 4 motor electric car we could probably run the normal brakes at like 90% and then control the last 10 ish % with the motors, since computer and electric components can reach the GHz speed unlike mechanical systems
there is an idea in some racing schools where your left without ABS for most of your schooling and introduce abs towards the end as a human with abs can outperform just full break force abs
You never said : don't try this at home
I am gonna try this
jokes aside, good drivers should try this (in a safe and responsible manner!) to see what it's like and not be scared to rely on it if an emergency arises 😉
@@SpaceMissile ahh . Don't worry i will never do this in a unsafe location. I not the best driver ☺️ . I wanna be one . I wanna try this on a safe , empty ground . I wanna destroy my tyres
I live in Sweden and when we're taking our drivers license one of the onroad tests is the ABS. Obviously in a controled environment or a wide road with no other drivers around. And we also have a seperate tests which involves hasards such as aquaplaning, animals etc, and here we also test the ABS.
Rock hard ABS
Tommo !!!
One thing I've ran into with ABS on, or at least the traction control systems. Is that when I am trying to slow down for a turn in icy conditions is that the traction control (controlled by ABS) likes to keep the vehicle going straight despite the direction I'm trying to turn. I've had a few times where I nearly ended up in the ditch because of that and ended up turning the traction control off to make those turns.
Worth noting, with the system off, I could get the car to make the turns at the slow speed I was attempting.
To quote my vehicle dynamics prof: "Unless you can actuate 4 independent brake pedals 800 times per second to correct the braking force per wheel, you are worse than ABS"
Would be amazing to see the same test on a loose dirt road! The saying is that ABS performs poorly on loose surfaces, and I am wondering just how true that is.
abs will roll you into the bushes at 5 mph in the snow because it never locks all the way up to actually stop you. it slows and slows and slows and slows aaaaaaaaannnnnndddd wait a seconddddddddddddd okay youre stopped... you couldve stopped 4 feet sooner by just locking all fours at said 5 mph
can second that. ABS is terrible on snow/ice. it keeps the car straight, but stopping distance is way worse
@@bigbud4sure ive seen many an accident on youtube where a slide (typically off a highway following a fishtail) would be checkmate with abs simply because you cant lock the wheels up and continue sliding to a stop in a straight line. its a very rare situation so i get it, but its still completely unreasonable to me that i can physically avoid a crash but a computer wont let me
the only time ive ever crashed a car is with abs on dirt roads. absolutely horrible and will just chatter the wheels if the tiniest bit of slip happens
Lots of magazines have done this test. Results were wildly inconsistent, but did often win without abs. Problem is, you loose all steering control.
ABS wasnt originally designed to stop you faster, its there so you maintain control of the car. Much more important 99%of the time.
I thought you'd get closer, and maybe beat it on ONE attempt, but you made an interesting point I hadn't thought of, ABS has control over each individual wheel, and I think that's going to be the big difference. Aside from the one time I freaked out the ABS on my BRZ at the track and got a flat spot, my already high trust in ABS is now even a little higher.
4 wheel abs requires huge power to rear brakes, more than you would actually need without abs. Another factor is the pedal feel and the master cylinder/booster setup. Only time taking the fuse out works is when stopping on ice and you still lose consistency every time
Now add some bumps and dirt on the road and enjoy 50-60 meters with ABS and still sub-40 without :) It would be a great system if it was allowed to overpush it and lock some wheels when needed. I drive for more than 15 years and still prefer to always disable ABS on my cars to always have predictible brakes and don't deal with glitchy computer in critical situations. The only exception is a race track as it's to expensive to buy new tires after a single wheel lock at the high speed :)
Great point bringing the abscence of braking Bias adjustment. Never noticed the relevance of it in that perspective.
The answer is yes. Skilled individuals with great feel for the vehicle absolutely can.
Overall, ABS is a great advancement. It is also worth considering that not all ABS functions the same across various models. Also, at least conventional ABS that I'm familiar can reduce braking effectiveness on loose surfaces like snow or gravel. Maybe there are some recent improvements, but I don't know.
Off-road ABS exists and has for a few years. It’s prevalent on bikes mostly. And the off-road ABS on a 1250GS outbreaks almost everyone
I would expect that the loose surface tuning in modern cars with traction control is far superior to basic ABS in early cars that only had ABS, particularly with the move to compact SUVs over sedans - for all their faults compared to lower riding compact cars manufacturers are tuning them to handle low traction surfaces.
Thankyou for proving all the people who say ABS doesn't reduce braking distances wrong! I have always hated it when people say that as they are assuming that you never lock the wheels. Coefficient of friction is much lower than coefficient of adhesion, which is why locking the wheels increases distances. Imagine how much worse the human will be if you now keep changing road conditions with water, gravel, mud randomly added between tests.
No one says it doesn't reduce braking distances.
We are saying humans CAN do better. And they regularly do. Look at the top GT3 drivers. If their cars use ABS, braking distances go up. Why? Because ABS REQUIRES the tire to lock up. Those drivers can ride the line so well that ABS activating does a worse job.
ABS WILL catch lock ups faster than humans, which is why GT3s still use it. But it is still NOT the best way to brake for a skilled driver.
The only time ABS does better than everyone is if the tires lock up. Then yes. ABS is better than all humans. But as far as only accounting for braking distances? Humans are capable of doing better.
Would be interesting to see time differences and consistency between using TC and no TC mainly on a wet surface, always wonder if its a strategically advantageous to use it on a slippy surface despite it feeling slow.
Also no tc on awd
I would love to see this test repeated over different surface conditions (damp, wet, snow, ice) and different tire/brake setups per condition. I'd wager the stock ABS system is optimized for stock braking/tire components on dry pavement and would significantly struggle on say performance wet/dry tires on snow versus a competent driver.
It would still best any human in damp or wet scenarios. I suspect the human only control would have a more favourable outcome in snow, however.
@@skylined5534 I'd agree that damp/wet on stock suspension and tires the ABS most likely wins, but I honestly don't know what the effects would be with high-performance suspension tires on a stock ABS module. I've empirically (anecdotally) validated on several cars I've driven that I can stop quicker on compact snow/ice. That being said, I think it would also be neat to test a timeline of ABS systems (although that would be much more difficult to control for i.e. how do you put a 2023 ABS system in a 2001 Miata or a 2001 system in a 2023 Miata?).
I think I saw a similar video many years ago on a honda CBR, where a professional rider could not get close to the ABS.
The fact that you can MASH the brake and get a better result in any situation than nearly any human is also the reason they made it mandatory on cars.
It is not mandatory, there are several sports cars that do not have ABS because it is actually better without when you know how to break.
@@a64738ABS is mandatory on passenger cars and has been since 2004.
I'd have cut the first two results from Scott. He just had to discover how this is done. And I'm surprised how close he could get to the numbers with ABS on at the end. Thanks for another nice test! And I'd like to second the proposal from Paul Keeble. Is a race driver (Scott) able to stop faster, if he tries to brake at the edge of triggering the ABS, without turning it of?
I think that leaving those in is part of the point of the video. He has years of racing experience and it still took him a couple of tries to get close.
like they said, in real life you don't get to sail straight through the kid who stepped into the road, say "oops! sorry!! I didn't quite estimate the required brake force correctly that time" and have another go, road conditions, tyre condition, tyre and brake temps change all the time, you're always going to either get it wrong the first time or be lucky to get it right the first time, meanwhile with modern ABS systems you'll pretty much always get 90%+ of what the brakes are capable of at any given moment.
But that is the huge advantage of ABS it gets close to the limit, first time, every time.
@@RWoody1995 yeah youre right. you could outperform an abs but then you need conditions that arent given in rl circumstances. humans are imo always capable of outperforming car electronics but are mostly never capable to do it when its needed. but also im for learning to drive without such assistance, like learning to brake if the system is failing. i learned driving a bike without abs. i often wish i would have got one but i dont want to relie on such a system. nice to have but mandatory to be able without!
thats why i trained braking on the bike. if you relie on assistance you shouldnt have a license because you are lost without it.
sadly driving schools are to modern and if something fails YOU WILL fail. so sad..... and thats in germany where laws get out of hand. and every fuckin car should have so much assistance that you shouldnt even have to do more then steering.
relieing on a machine is imo more insane then driving without by far. i also tried drifting in the snow on the bike and i learned a lot about saving my bike if the front starts slipping and how to "power"drift. okay 125c c15hp and such a rough idle that 100% throttle at idle meant that the wheel broke lose even though the power wasnt enough at 15hp if i used the gas softly. very interessting experience!.
think about it , half the torque and by far less power and the kick was enough to lose traction while full power and torque wasnt enough if delivered smoothly.
ever had such an experience? i mena kinda logic. if you drop your clutch hard they tires just get ripped of "before they can grip" the surface (even though that this is scientific wrong because of the torque spike not the missing gripping because it always has traction at some degree)
"I'd have cut the first two results from Scott"
So you'd fake the results? Nice.
I generally advocate for abs and traction control for regular cars… but I’m really surprised neither could beat ABS with that many tries. I didn’t consider the electronic brake force distribution though and guaranteed that will make it impossible to beat.
I am more than happy to have both but for traction control. Just please give me a button that allows for 100% on and 100% off.
The cars braking system isnt optimized for non-wheel-independent modulation, even the front rear bias could be massively off

Abs yes, 100%. But traction control is just dangerous imo.
ive had (on mazdas) several situations where mid corner the tc kicks in and tried to put me in a ditch. When i was no where near breaking traction.
Its like halfway through a corner the car just attempts to straighten itself out by braking individual wheels while the steering is still pointed where i want to go. Its extremely unnerrving and imo, downright dangerous.
Wait till you try abs and stability on a motorbike, a gamechanger
Another thing to consider is that modern ABS also controls the brake bias, in our RX8 race car is you disable abs it will put the braking bias to almost 100 front as it thinks something is really wrong with the system and you will destroy your tires as you understeer off your line.
My 1988 RX7 FC doesn't care at all if you pull the ABS fuse and will function as normal minus you being able to lock up the wheels at extreme braking. I would not be surprised if your Miata did the same thing, it being modern.
There is one test i would like to see. The same test on gravel (or snow), which atleast in the 80's/90's was claimed to be better without ABS. Albeit the abs then was worse than now. The same was said for snow. (that was the reason audiclaimed for having a ABS shut of button in the dash at the time)
for sure in the snow condition you can beat the ABS, with experience I barely engage ABS anymore... It's icy well just need less brake a longer distance. I did the test on my way to work one day and if a floor the pedal for maximum force it just pulse and barely slow the car to the point of blowing a stop sign but the car was still straight. on the other hand, if I brake until the ABS pulse and come back a little to avoid it kick in, it slow a lot better to the point it the seatbelt that retain me in. I did it on winter tire more wider (235 instead of 215 with the most wider contact patch for that size) and I'm in Canada... Also the sound the snow make during braking is important to know the grip, if it slip the sound goes away(or you are stopped) but when you brake the snow crunching noise goes higher and higher until it slip. The snow on the ground make a little mountain in front of a tire during braking
@@ItsJust2SXTs yes, still like to see a video of it 🤙
ABS developer here. Well, on deep gravel or snow, locked wheels can in some scenarios dig in and collect a wedge of gravel in front of the wheel, which may stop you very quickly indeed. One downside is that if you happen to have gravel only on one side of the car, the resulting one-sided gravel wedge will spin your car sideways, digging the now forward facing side wheels into the gravel and flipping the car over. Also, modern ABS on offroad cars can be set (manually or automatically depending on manufacturer) to some offroad ABS setting that then tries to build a wedge, then roll over it, build another one and so on. Beating ABS may still occur when offroading a car that was not made for it, but then you will have bigger problems.
Thing is, even if a human _could_ beat ABS some of the time, it is the consistency that is the issue. You might be able to do it well when practicing, but could you still do it in a panic stop situation? It has to be instinctual, and that take a ton of practice, if its even possible at all, as I've seen plenty a race car driver lock the brakes and not pump them before collision.
Much better than the older video. But still flawed. The MX5 brakes are designed with the ABS in mind. So who knows what the front/rear bias is. Bypass all the electronics, add an adjustable proportioning valve, give the drivers a car that can be designed to work without ABS. Even with a poorly adjusted system, an average driver with no experience driving non-ABS cars was able to get within 5m of the ABS baseline. I bet a properly designed system would let the pro get within striking range of the ABS.
You shouldn't compare ABS-enabled car to ABS-disabled, but to non-ABS car with mechanical brake distributor instead. Removing ABS fuse makes your car brake worse than non-ABS car because of absolute absence of brake distribution. Brake distributor installed in the rear end and connected to rear suspension will adjust rear axle braking force according to suspension position - the more car leans forward, the less brake force is applied. Being set correctly this system allows to brake much better than ABS, though you need to get used to it on specific surface each time.
We also have to remember that ABS has been refined for a long time now - early ABS were a bit crude and can probably be beaten, but any vaguely modern system is realistically unbeatable.
Much better video than your last one. I'm also surprised to see by how much you couldn't beat the ABS - I've been in situations where an unwanted ABS intervention genuinely seemed to reduce the braking force. As others have posted, this isn't necessarily a direct with/without comparison as ABS-equipped cars generally have a greater rear brake bias, and heavily-servo'd modern brakes make threshold braking more difficult. An interesting further comparison might be a car that was available from the factory both with and without ABS - The MK1 MX-5, perhaps? Although a thirty year old car probably isn't a great example of the state of modern ABS technology!
@drivenmedia it's a scam 👆
this test is flawed because youre attempting to use a system thats designed for use with ABS, without it. it is not designed for that situation and thus, is incorrectly biased. im certain that installing a proportioning valve or two would change the results of this test. he managed to get very close to the abs distance with a flawed system for manual braking.
i dont remember who it was but many years ago, there was a F1 driver who easily managed to out brake an abs equipped car.
Intresting. but a proportioning valve can be used with an abs and enhance braking even more. so again you do not compare the same things.
as far as the f1 driver, if it was over a decade ago, the abs technology was far less advanced and could not handle each tire seperately. with today technology, there is no way to beat abs consistently in scenarios like this(emergency braking on a straight line).
The abs does not lock and unlock the wheel at short random times. It consistently keeps each tire at max grip, that can offer up to 20% more efficient braking power than if you could handle perfectly 4 wheels at the same time. Streetwise, it can't get better. In track is a whole other discussion.
Also worth noting that this is a known braking point, you can anticipate it. Whereas ABS is even better for the times when you didn't - or couldn't - anticipate the need to brake aggressively. Even if someone got close on-track doesn't mean they'd get close on eg. drive home in dark in the rain after a long day
As a simcade player I'd say I can (with certain cars though, and I still leave ABS on because consistency), the main point to turn it off is when you don't have to go to zero but want to have best steering control when braking
What about the loose surfaces (like snow) where locking wheels can actually have an advantage?
I was thinking the same thing. On dirt ABS can send you off the road, almost like having no brakes.
A lot of cars have a snow setting where abs will work differently.
Could be interesting to test the difference in time taking a corner with or without abs
I have done the same test and my results were very different. My pedal action is different. I come to threshold and back off ever so slightly, and then increase pressure slightly as I come to a stop. These results were consistent with in the vehicle driven. Most cars I was quicker.
I guess the miata is just better than u bro
@@egullSZ Not me. Maybe the driver in this vid. I use the e-brake and pedal modulation to stop the shortest. Another trick with the e brake is when going over big bumps you can put some tension on the rear springs as you over to smooth the transition. This allows you to go over things way faster without catching air.
the same idea but in a corner could be fun and we will learn few things (weight transfer, possible under-steer or over steer, etc)
Now I would love to see a brake bias system installed and watch the guys fiddle and tune it just right to see if they can beat it
To be fair, I think it is way harder to brake with a car that has a braking system, which is optimized for ABS and has ABS turned off, than with a car that does not have ABS at all. It is way harder to modulate the pedal imo. So to me it seems like this is an unfair comparison for non-ABS-braking.
Interesting
For brake by wire I'd agree, but this is still pushing on a standard hydraulic system so it should be representative.
@@Southghost5997 It's more about the brake balance and the sizing of the master brake cylinder.
@@Southghost5997 brake bias/balance will be all over the place though.. As the locking up of different wheels each time shows.
You won't beat ABS anyway. No car allows the driver to brake individual wheels.
ABS is not to achieve maximum braking performance. ABS is to locking the tires from breaking traction, skidding, due to issues with the driving surface. In optimal conditions, a trained driver WILL outbreak ABS. However, regular folks usually won't, and in wet, snowy, or icy conditions, in conditions of uneven surface or unimproved roads, or when attempting to brake and maneuver at the same time, ABS will outperform a person.
I tried this test from 100kmph in my nonABS 1984 Mitsubishi hatchback and got 27 metres on my first run and 29 and 30 metres on 2nd and third attempt.
Not bad for 40+ year old car with only a drum to disk rear conversion.
Is there anyone monitoring the entry speed and when braking occurs? Looks like the non-abs runs starts braking a lot earlier than the cones. Also a small difference in entry speed makes a big difference in stopping distance. Energy is proportional to velocity squared so a small difference in entry speed is not negligible.
The bigger difference will be when you brake and turn at the same time
Do a comparison between Modern ABS and Takumi.
then there is racing ABS which allows to trim it depending on grip.
another thing, some guys claim better braking in an abs car by modulating the pressure right at the limit where the ABS doesn’t kick in and lets the wheel free a little bit
Are the rear brakes more effective with ABS? Street cars have brake balance towards front, so without ABS the front brakes lock while the rear brakes are not biting yet?
You guys should try this in the snow as it will take more time for the wheel to unlock and because abs is so aggressive you could probably beat it by a lot…
During driving ed we we're on a slippery course and compared braking with and without ABS. We turned the car off to achieve braking without ABS and we did not let off the brakes when decelerating. Without ABS resulted in a shorter braking distance, but the car also did a 180 doing it so not ideal to do in traffic.
@@ra420m bro why tf was my behind the wheel not fun like that
Since you have only one pedal for 4 tires / breaks you have to tune the break biases perfectly to beat ABS which can control the breaks on each tire individually.
One thing to consider is that race cars with no ABS have much shorter travel brake pedal. It’s easier to modulate the pressure in MM rather than 10 CM for a road car. But for a road car not suitable as they require a lot more leg power
This car is designed to have ABS, there is no brake proportioning valve and may tend to lock rear wheels. In most non ABS cars you have some sort of BPV, either constant pressure, or variable one based on rear axle load to avoid going sideways.
You should done a comparison in the end with abs on, just to see how much the wheels been degraded from all those lockups, probably would have been wors then the first abs test
A 5m average behind abs.. I'll stick with my all hydraulic non electronic , manually adjustable bias brakes. Like the guy said abs can only help when trouble happens. A human can predict conditions and prepare. Abs can not. Abs just makes drivers reckless because they never Learn the limits of their machines and just expect the abs to do all the work.
Should be one run locking up the tyres at all for reference!
But nice challenge
That was a great test and actually amazing how much technology can aid in making vehicles safter. Thought pros might beat the ABS during braking when I saw the title and was curious, turns out they don't.
Why would a professional driver ever be able to beat a system that individually controls the breaking on each tire 15 times a second...
@@mica410 ABS is usually tuned to attain a specific slip ratio on the tyres which is determined for the stock tyres usually; but this value changes as the tyre wears. Turns our ABS wins still.
Have you replaced the tires between runs? Because flatspotting can seriously hamper breaking performance, and the first guy flatspotted all 4 tires for certain.
Forgive me for my ignorance, but if we aren't worried about controlling the car under breaking and we'are strickly worried about the stopping distance, shouldnt you just go for a full skid? Wouldn't just slaming on the breaks and the the tires going full lock actually help with stoping distance? Or was the test also including control under breaking? Please someone correct me on this.
i did this test 10 years ago and i handily beat abs. surface had less grip though.
now on mud... abs will just try to kill you every chance it gets by taking ALL braking away from you
I think another variable for the ABS being on the car or not how sticky the tires are. If you're in a race car that has racing tires that are more sticky and give you more grip you're less likely to lock up at the limit if those tires can scrub your speed fast enough. Considering most street tires are pretty junk when it comes to heavy braking anyway
Actually, I have a Polo 6R with ABS on, and when I put pressure on the brake pedal just barely before the ABS starts to work, I feel more deceleration than with ABS, the pressure must be accurate otherwise the ABS will work or you will lose break power if you don't push enough, adding to that the temperature is always changing and the road rugosity too, also most people will brake hard when a dangerous situation occurs and by reflex everyone will rely on ABS in that situation.
Disabling ABS also disables brake force corrector... So for proper test u should use car w/o ABS from the factory and similar model with ABS equiped (cars back in time had ABS as option).
i'm not surprised about this. abs is just awesome and every car should have it, even performance- and fun track day cars. it doesn't spoil the fun, it just adds something you can't accomplish yourself anyway
Interestingly they demonstrate this at the Porsche experience, and the best braking comes from having ABS but modulating the pressure slightly when it kicks in - combination of ABS and driver skill (not just mashing the brake pedal) wins out.
I notice the Mazda is locking its rear wheels, which is not a good thing on a road car, probably from lightening the car - needs a brake bias adjustment then it might stop sooner.
As other comments stated. This car was engineered for ABS. Cars engineered as non-ABS have much more pedal feedback and have a better setup brake bias and brake balance. A car with ABS doesn't mechanically limit the force to improve brake bias, rear brakes and front brakes will be setup for maximum force and let the ABS manage the rest.
This test is still very scientifically sound. I'm just saying that a car with no ABS from factory is totally different from a car with ABS "turned off".
But and interesting test would be a car from the 80s/90s where the ABS was an option. So the car was engineered for no ABS but had it has an option or a trim.
If you had individual control over the front and rear brakes like on a motorcycle, I think you’d be able to stop a bit quicker. The problem is that cars tend to be built for convenience.
But emergencies aren’t convenient, are they?
👆 it's a scam
@@STax9 Oh, I know. These scams are everywhere on automotive channels. Says something about how gullible car geeks are, I guess.
I don't think anyone can beat ABS with a fixed brake bias: without ABS braking systems are optimized to lock front and rear axle at a high deceleration (usually around 1g) and with the front axle locking first because it is safer (as we saw in the video, when the rear locked first he had to a huge correction on the steering), staying as close to this point will grant the maximum performance, but it is still with a fixed ratio between front and rear. With ABS on and the front wheels would lock, it will prevent not doing it so the wheels can apply the maximum braking force to the ground, but the rear wheels can still increase their braking force till the point they would lock too. This will grant a higher deceleration that is not achievable without ABS, since the locking of an axle cause a drop of the force that it can apply on the ground.
A good test, but the only issue is the driver is not always going to start braking at the same spot each time. You need something like the old style chalk gun to indicate where the brakes were first applied. Will's third test looks like he started braking well before the cones. At 3:40 the front of the car is dipping and braking starts very shortly after.
Can a Human BEAT ABS?
yes, but not reliably or on command or in most cases. there's a reason it's considered a performance enhancer in racing. however perfectly controlled consistent braking force IS superior to pulsed actuation, we just don't really have a technology for that yet.
I have a feeling it varies depending on how old and crude the ABS system is, and perhaps tyres?
The only reason I say that, is that in my autocross car (an early 90s Mazda 323F) I had a problem where once I put semi slicks on it, the ABS seemed to really have a bad time with things, and reduce brake force too much, unplugging the ABS fuse made it much easier to make a hard stop in the gate at the end of an Autocross run, seemingly to the tune of like 3m or so shorter...
Looks like we gots a scammer here..
also, when you pull the abs fuse, you have no brake proportioning valve/fromt rear brake bias
Just wanted to say I keep seeing this video and every time I really wanna press it because of the thumbnail but I'm just not interested in the topic. So just wanted to inform you that the thumbnail is REALLY good in my opinion even though it may not get as many views.
Id say in the winter on snow/ice...ABS off can be better. if the ABS is too sensitive or the road is too slipery, the car just wont slow down at all. The ABS just keeps releasing the brakes
But thats a car to car basis, not a blanket statement
Can you do a video on rather down shifting while braking effects the distance vs braking without downshifting
The driver does not have the same access to the braking system as the ABS unit has. So even if a human was faster and better than a computer, they simply wouldnt be able to make use of it. Its about the same as with traction control or ESP. The driver does not have the hardware to tune the amount of torque going to each driven wheel individually, he only has 1 throttle and 1 brake and maybe 1 clutch pedal.
You relatively often hear people say that racecars dont really have any electronic driver aides, so its just a skill question. No. (Some) Racecars dont have ABS because theyve got absurd amounts of grip. Plus, the drivers are constantly working at the limit of their vehicles, the last thing they want to happen is for the electronics to suddenly cut power or apply the brakes on a wheel mid corner.
IF (big IF) I could turn off the ABS on my truck, I could stop it probably 30 feet SHORTER without the ABS than with it. I removed the ABS from my 1994 Suzuki motorcycle just for that reason and to remove the 30-odd pounds of weight that it entailed. I did a "Smash-thru test" on the Suzuki. I test stopped the bike as fast as possible WITH the ABS and set-up a paper barrier at the EXACT point on the track where I had stopped. Then I removed the ABS from the bike and stopped it as fast as possible without the ABS and measured my distance from the sheet of paper- about 12 meters, then I moved the BRAKING POINT MARKER 13 METERS FORWARD to see if I could STOP before HITTING the PAPER BARRIER with HOT TIRES AND BRAKES. I did 15 times with the rear tire in the air every time on video about 250 mm! (A "stoppie"). I never touched the rear brake at all. I'm VERY good at braking on a bike or in a car or truck.
Abs acts also like a differential in braking, not just auto brake distribution front to rear but mostly between near and far side wheels.
Iinteresting video.A few years ago I went on a skid pan, old Granada soaking wet, and bald tyres to make sure it skidded. It had switchable abs and they taught us cadence braking which always worked better than the abs. Does that mean abs is less effective with really low grip or maybe a more modern abs just works better?
if on dirt roads, you must turn off all assist, ABS will not allow the tires to dig in the ground and push material to pile infront. TC will constantly cut power to wheels that actually need it and upset balance, specially in a sand trap situations. saw a 2016 dodge ram at the beach once burning through its transmission because TC block power, a flat bed had to pull it out.
Apparently ABS is bad on slippery surfaces such as snow and ice and probably dirt because even light braking will cause your tyres to slip, and ABS will reduce the braking trying to get grip so much that there's barely any braking at all.
Thank you for revisiting this test. That said, I wonder what else was disabled when you pulled the ABS fuse? And what is the hydraulic brake bias? If the ABS is designed to compensate for a less-than-optimal hydraulic brake bias, you may be setting yourself up for failure.
some more modern cars actually adjust brake bias on the fly to get optimal balence
seems like there is some mechanical complication at hand

idgaf abt stopping fast at the end of the day if i cant lock up my brakes i cant hook my nose down thru the corner and oversteer into the apex making me slower
Does the car have steel or carbon ceramic brakes because the stopping distances from that speed can be impacted by about 10 meters if there are steel brakes.
Why would it matter what brakes the car has. The tires lock better brakes won't change that
I am surprised too. I thought Scott would be much closer to ABS, if not better. I'd be interested to see how that experiment translates to a track lap time though, rather than straight line braking. Does ABS help lap times, or can drivers do better without? I may have to revise my mis-conceptions...
ABS shortens braking distances so even in a straight line, on a track, it has a huge advantage, being able to brake later. You can also keep braking during turn-in, and although threshold braking is probably the way to go if you're a seasoned driver, the casual trackday enthusiast does nothing but benefit from ABS.
Watching RUclips adverts combined with Brilliant adverts really slices up the watching experience. I really miss the days it was only RUclips that shafted you with ads. Now we get shafted from both ends.... And not in a kinky way :(
So if you train yourself to do this with your car, and you get exceptionally good at it. You are almost comparable to abs-braking. Unless it's a super stressful situation where you forget all you learned.
An old timer said that modern cars with techonology is rubbish, but even he admitted that ABS, traction control and airbags were a life saver. The rest is just uneccessary trinkets.
Even so, if you drive very old cars it is worthwhile learning how to brake properly just to increase your odds of surviving.
I would retry this on a older car as newer car use the abs computer and pump to manage brake bias, so you get inconsistencies in braking performance with abs. Also stock pads do not give enough modulation and feel for me.
7:57 ah you see, you can't just have Scott casually saying he beat launch control and then direct us to the video at the end. It all got spoiled XD
IDEA: make a car that can brake each wheel with a separate lever, or perhaps front and back brakes(or left and right)
In cars it makes sense to have ABS. The computer can control each wheel individually while you cannot. On motorbikes however you can, and I've found that on most bikes the ABS setting is a bit too conservative, and you usually can't turn it off except for higher spec models. On a bike your primary front brake is used with your hand, so you can modulate a lot better. It's kust anecdotal but personally I'm more annoyed with ABS on motorcycles.
the main purpose of ABS is not about shorter break, but a controllable, consistant and less dependent on surface. on ice you probably can beat ABS in straight-line braking, but you will lose control 9 out of 10 times. when you not locking up (and that's what ABS doing), you can control and steer, and it can save others life, property and your car.
I think you should do the test but with a british trained Advanced driver ( by British i mean the UK advanced driving course and training). By the looks of it, none of the drivers used cadence braking which is like ABS but for a human input rather than a computer doing the work.
Should have put the fuse back in at the end to see how much tyres and brakes were affected.
Also it would be good to have a data logger onboard to see what the actual numbers are because it looks like the front dips sooner when doing most of the abs runs.
It should also be noted that this will be dependant on surface, traction available and most importantly the abs system itself. Some of the early systems were atrocious and easy to beat. On the other hand some of the new stuff would make that system look like it wasn't trying.
Electronics have come a very long way since the 90's.
Other comments have mostly said it, but 4 channel ABS/ESC systems (where two isolated hydraulic systems are separated diagonally, not front to rear) are designed specifically to work only with the control system functioning to adjust bias. Without the system functioning you typically end up with a catastrophic rear brake bias. This video proves pulling the fuse on 4 channel diagonal hydraulic brake system is not good. A proper test would be a car offered with ABS optional vs not optioned, NA Miatas would be good for this, although most early ABS systems are probably 3 channel, treating the rear wheels as one input and potentially retaining a front/rear proportioning valve that would feel more natural even with the system not functioning.
This doesn't even demonstrate the biggest benefit with ABS (although you did mention it) . The car is still steerable no matter how hard you brake, while if the wheels lock up you can't steer. An inexperienced driver or even an expert driver might forget to ease of the brake when needing to avoid a sudden obstacle. Leading to the car losing traction and continuing straight ahead.
This is something we learn and get to try ourselves while getting our licence in Northern Europe along with driving on ice.
U guys should do traction control and stability control
I would like to see if the same would happen when one tries to stop, from 30 40 or 50 kph.
The point at 5:40 is exactly why ABS is superior. It can brake on a per wheel basis
If you have to go on a Police driver re-education course you will discover that the official line is that ABS does not alter the stopping distance at all, but merely allows you to steer and maintain control under braking.
This is the official line and they allow no argument.
Just as they argue that those stopping distances in the Highway code are still valid and accurate after 75 years.
Short Answer: If you focus, maybe you can brake close to ABS.
But no matter how professional you are in traffic, there is always the possibility of panicking and pressing the brakes all the way.
btw the fuse diagram is in the inside of the fuse box cover :)
