Why does it feel so fast when you’re driving a kart?
Why does 50 mph in a kart, feel so much faster than 50 mph in a road car on the motorway?
F1 drivers often say that karting is one of the closest things to actually driving an F1 car -- but how is this possible if kart is travelling at a third of the speed?
Well, today, I’m going over the science to explain why karting feels so quick -- and I’m writing the morning after a karting session.

Because your low to the ground, un protected, it's bumpy/ noisy and the track is small and appears to go past quickly. Same as how a rollercoaster tricks your mind even though you can drive down a highway faster and feel safer
it was a rhetorical question bro. Its all explained in the video
Tbh, my kart can do more than 3 Gs on quali-tires in the bends. And with the tiny seat there is not much support. It just feels incredibly fast.
@@Gino_567😂
First experience on a motorcycle is similar! But then you get used to it, karts always feel fast 😊
Great, no need to watch the video now! Thank you brother
4:05 In this specific example, the narrower field of the train's view makes the speed seem slower NOT because the field of view is narrower, but because that narrowing is achieved via zooming in (increasing the objective's focal distance), which has the direct optical effect of shortening all distances in front of you (e.g. if you zoom in 2x, all objects look as if they are 2x closer), which literally means that you are traversing shorter optical distances during the same time period, which directly translates into optically-lower speed.
Had the author narrowed the field of view by simply blocking out the peripheral parts of the image, the train would feel just as fast as before.
10:09 whats the movie?
I'm pretty sure it's Rush.
Small nimble cars >>>> heavy fast cars
(Looking at you F1 👀)
Yeah it is a shame that most sportscars weight significantly more than 1 ton these days :( 2024 miata has curb weight of ~1100 kg. golf gti mk1 was 810 kg. of course crash protection is MUCH better in the newer cars.
@@meltdown6165 how are you meant to get a car under 1 ton lol.
even some carbon fiber cars don't weigh under a ton.
Nowadays it is nearly impossible with current regulations. That mk1 Golf had neither a cat nor ABS nor airbags. You could drop 2.5 million on a GMA T50 I guess? Otherwise only track focused cars like Catherham 7 or Ultima RS remain, I don't think they are very good as daily drivers.
I'm just saying that slinging around fatass cars is fun as fuck. The obsession with being light is funny sometimes
@@linkplays2952 a Renault Twingo is below 1 ton ;) or a dacia spring electric if you rip out 30 kg of unnecessary interior.
Think that's why so many SUV drivers seem to be speeding? :)
I don’t know where you live, but where I‘m from I literally have never seen any SUV driver speeding. Usually they drive 20 under the speed limit.
@@florianlassnig9769 I see them speeding all the time here in Germany.
Here you see audi, bmw and merc SUV going 20 over in Poland@@florianlassnig9769
For me, it's the realization that a good kart can take a 90° corner out of a straight at full throttle. The grip is unreal.
just had to comes to terms with this yesterday as it was my first test session. First race in a few weeks, hoping for some more trust in the kart soon.
Kinda. The rental ones generally have super hard tires that last forever. Racing kart tires are something else
@@riccatdozanotti I have never driven a rental.
@@TheDwightMamba you should try to feel the difference. It requires different skills but it's fun
@@riccatdozanotti , I imagine it feels close to tired tires, which is heaps of fun.
You forgot at least one major aspect. The incredibly short wheelbase makes the cart steering more responsive/twitchy. It also makes the time between bumps hitting the front and rear wheels quicker which you will perceive as speed.
Didn't though of it but that's definetively true!
Great point, new video ... Haaaaaaa
6:56 I never thought I'd get to say this on a Driver61 video, but "I'm VECTOR! because I have both DIRECTION and MAGNITUDE!"
Okay, but watch out for that tip to tail analysis.
Well played!
"OH YEAH" *starts humping the air*
The thing I hate the most with karting is when the car starts to vibrate. The kart I drove as a kid used to vibrate so much it blurred my vision. It made 10 year old me absolutely terrified driving at max speed.
Guess you had a taste of 2022 ground effect
In my first experience i was more concerned that the loud engine would explode rather than winning or crashing.
In my first experience I was fully focused on going fast, and didn't care if I was going to crash.
@@trinity1969 I wish i was like that lol.

🤣🤣🤣🤣
The picture at 33 seconds is me lol. I’m in the back running my number 7 plate 👍
Really?
Its true, i have broken a rib in a kart, due to i rented a kart that with a seat that was way to big for me, and got into a pretty compettative fight with a friend, both of us Simracing fanatics thus we went a bit bonkers offcourse showing off to each other who was the fastest, so i was bashing around in the seat like crazy.
After several sessions my ribcage was so sore, i coudn't go on, and i went the next day to the hospital where they told me i had a broken rib.
But then it was FUN!!!
My broken rib story is almost identical. Go-karts on my birthday with competitive mates. I thought it was just a bruise until I sneezed in bed the night after the race and it finally cracked. Had to get Dad's help to put my trousers on and then off to A&E.
“I started racing go-karts. And I love karts. It’s the most breath taking sport in the world. More than F1, indeed, I used to like it most.”
- Ayrton Senna
and "it's as hard to drive a 125cc shifter kart as a F1 car"
[I may have the wording off on that one, i couldn't find a copy of that quote to confirm it exactly]
Once i tried a Kz. The most terrifying thing ever. Like, dude i do rental karts every month, and drive a miata, but the KZ is just insane, both from the perception of the 2 stroke buzzing , the acceleration, the inmediate response, the vibration...
I would never have the guts to race KZ's, I cant imagine how terrifying an f1 is
I drive Rotax regularly, which is much slower than KZ2 (although as fast as KZ2-fitted kart in the corner), and once you get used to it and really feel the limits, it's quite safe. Basically, if you control yourself well, you never crash, even if someone (or multiple someones) crash or spin in front of you.
It's not perception. A 29hp racing go-kart is equivalent to a 300hp[1 tone car] -450hp[1.5 tone] car. With only one gear and more grip the speed - and more importantly the control - is real. He forgot to mention the absence of differential.
@@korgmangeekCan you please explain what you mean that a go-kart is equivalent to a 300 hp car? I don't understand in what way equivalent. Thanks
@@ok.-ok. I forgot to write the weight of the kart: 50 kilos vs 1.000-1.500 kilos of a car. Porsche 911 1.500kilos.
The power to weight ratio is comparable to super car. The grip is comparable to race car.
@@korgmangeekgo kart is 175 a 150kg
Perspective and field of vision.
Perception
Sensory Feedback
Vibration, noise, wind.
Perhaps experience a bit too.
Really interesting as always.
05:51 - that's a good analogy. You think you're going really slowly when you're in an aeroplane. But once you see another aeroplane go past you, you then have something to compare your speed to. And those other aeroplanes are (literally) flying at incredible speeds!
I’m a student pilot and the speed perception thing is wild as we’re learning to do landings.
65kt feels painfully slow right till we touch down and realise we’re doing motorway speeds on a very short feeling runway!
This is why when i was junger i wanted a fast car, but now i'm into dirt bikes bicycles and skis. Going 30/40 kmh feels really fast when you're tucking your elbows to avoid hitting trees, hearing small branches hitting the helmet and jumping around. Add some no fall zones and it will wake you up
Same man, nowadays i find more fun in mtb than I do on my fast car. I have a good simrig which is more fun than the real car to be honest.
Similar to the reverse effect I feel at work. I drive heavy equipment, trucks and buses. 55 mph in those feels slower than 55 mph in my car because when I'm in a truck or a bus, I'm sitting 5 feet above the road.
You should definitely do a video about 90s to early 00s karting. That was a very special era of motorsport, and sadly, Karting today has lost its soul hasn't been the same since. Anyone are curious should definitely check some videos out of races in that era highly recommend it.
Why has it lost its soul?
When you mentioned Jerk I remembered that one guy that always managed to quickly change someone's acceleration.
"in your typical sedan or saloon" *shows a sports car*
Lol
And specifically a Lexus lc500 in that
they feel fast because they are fast. don't think any of the ads mentioned that.
A month ago i bought brand new OTK with TM KZ R2 engine...this monday i go to race with friends...i am kinda scared...i never driven race kart...only some rentals...i have fast CAR... BIKE...UTV and all boys toys, but this 125cc karts are like next level shit...i tryed it only a little in my street, and it feels prety raw insane...can't wait this monday...i hope to get home all OK.😅😅
I remember i went go karting with one of my friends with some more professional karts ig (idk i put my phone on the kart with like a speedo and it clocked in at max like 115 kph?) One of my friends took a bump real bad and his kart was sent flying over the tire barriers 😭🙏🙏🙏
Absolutely brilliant video Scott! I love how you brought together all the factors most people would never consider in the driving experience. I have been driving/racing for 48 years and I learn so much from your videos. Thank you so much for all the work you put into them.
My first ride in a go-cart, was in a racing cart that a friend’s dad bought for $5k in ‘98. Scared the bejesus out of me…could do the tonne in only a few seconds. That was also my last ride in a go-kart…😂
Being able to see the front of the vehicle clearly also enables a better entry into the corners. Perspective and overall fov make a difference.
cars are designed for comfort karts are designed for fun thats the diference
I feel like I am going 2 times slower and I am one with the kart and I am just locked in and follow my lines and follow breaking points and just go for it and just make passes and go for the win cuz i was just at Daytona for ckna
This guy spared no details. Went as deep as describing as how your skin feels the vibrations in the ground. 10/10 video 👌👌👌
People think it's acceleration that race drivers love, but after a while you get used to it. It's the jerk that is the real joy. The initial turn-in, and then the switch at apex from brakes to throttle - that's the good stuff. Jerk junkies all of us!
Physically speaking velocity is a vector.
As a matter of fact when a car is moving on a road to fully express velocity you specify speed and direction.
Acceleration is the rate of velocity over time.
Great vid bro

Hey scott, I’ve been karting for a year but my forearms always hurt after sessions, how do you reduce that issue, maybe im not steering the right way
Usually it means that your are holding the wheel to hard
Relax your grip and think "smooth, smooth, smooth." Besides wearing you down physically, jerking the wheel or making constant corrections makes you slower.
They literally break ribs going around corners. Harder to drive than F1.
Oh and please don't compare your little 4 stroke sodi hire karts to the real things.
They are more than half the weight, engines 2-3 times more hp and super sticky tyres.
but what would I know
amen to that
More competition around feels even faster 😜
video about project invercion?
this is why I drive "camera pod" POV instead of "cockpit" in F1 23. still learning. I'll get there.
So, when you have a 'moment' and go to correct it you are going g to be too late as it's already happened, cockpit or nose view is the best, race with either of those and you will be better, it's how to race games better and properly, been there, done it worn the shirt.
can you please make more carting content, cause f1 and other things sure are pretty exciting but karting is the only thing I can experience irl so its be great to maximise my experience
For me why it feels fast is the same reason as riding a motorcycle, you feel the air rush and also the really unrefined feel
it was driving Karts in Europe which led me to my Lotus Elise here in America. Closest thing outside a Seven, plus it has a roof!
I never got his one hey. Sure 120kph feels scarier in a kart than a car on the free way, but i terms of perception of speed they are exactly the same.
11 minutes of explanaton and the answer is i never get this one 😂
"That's all pretty simple"
Try telling that to someone who believes the Earth is flat. They don't know what inherited motion is, they can't comprehend it, they think we should all be flying off into space if we're all stood on a huge spinning ball. smh
01:30 PC/console gamers have known this for decades 🤷♂😅 bumper cam always felt WAY faster than driver cam.
That FOV difference was crazy though, I never thought about that.
So... tiny, low cars are safer at what the driver perceives as high speeds, because those high speeds are actually lower than what the driver in truck/SUV would perceive as mid speeds. Sounds reasonable enough to me :D Driving around on the winding country roads in my old 785 kg Daihatsu at well under the speed limit felt like driving the Monte Carlo Rally at times, zooming around those corners at twice the speed in an Audi just isn't the same...
Racing boats has a similar feeling, plus wind in hair... 60 on water 'feels' fast, 100 is really fast.
Having done many years of karting with a 125cc shifter kart some 20 years ago, my 991.2GT3 feels almost lethargic around a track. Other Porsche guys dont believe me… 😢
Having survived to 74 years now, I'm amazed at karts lack of driver protection, no safety harness, roll bar or any other crash structure. Of course, without a safety structure, a harness would have not much to be attached to, the chassis I suppose. This goes back to early days of racing when the thinking was to be thrown clear of the car rather being in it when it crashed. At least they wear helmets in karting, but it doesn't protect you from a broken neck. Since the karts only go about 50 mph, you can be seriously injured at that speed. I know as I was seriously injured in a bicycle accident at an estimated 30 mph and I had gone over 50 mph before. I wonder how many kart racers injuries there are and how severe? Karting is for thrill seekers with no concept of mortality. Not me!
Velocity is a vector. Velocity has a speed and a direction. You've confused velocity and acceleration. Acceleration is a ². You can have an initial velocity of 30m/s, and then have an acceleration of 2m/s². Every second you travel, you're increasing your velocity by 2m/s. You don't need a direction for acceleration.
This is why small light sports cars (the MX-5 being the prime example) seem fast and manic when you're driving them, compared to something like a diesel hatchback. The hatchback may as well be faster than the sports car, but you feel like going a million km per hour in it.
Apart from all the reasons you mentioned, I think another reason is that unlike normal driving, you are now on a very small circuit, so it is action all off the time (any straight is a few seconds max) and unlike road driving you are driving on the limit of grip, which is much less predictable and harder to control once you loose grip, due to the lack of a differential and the very short wheel base.
And yes it feels fast if you are on a busy track as you say. I think it is because of your low eye height, and now you can often see even less far ahead.
In normal driving eye height makes a big difference in how far you can see in to corners. specially in the mountains.
Can confirm. Owning a road legal "kart" from Hethel, I´ve never, not once, gotten out of it and not smiled like a mad man.
Never driven a real go-kart...guess I really should?
In some way, perhaps louder engine sounds also help racing fans feel the speed of the cars somehow. So, the people saying the v6 hybrid turbo killed the racing for them is because they have one less stimuli to feel the race car's speed as it goes past them. Not only do they sound amazing, it is felt too...
So there you have it. Bring back the V-10s!!!
fun fact, the earth travels through the solar system at like 67,000 mph... and we notice nothing because the speed is both constant and there is no accelerating/deceleration... if the earth were to stop, half the planet would turn into bug-splats and the other half would get launched (although inevitably burn up) into space.... and some would slide a long the ground... think pencil eraser on sand-paper.
6:59
The more accurate statement would be:
accelerating at 10 miles per hour *per second*
(I think Scott meant _moving_ at 10 mph to the East)
But then we'd be talking velocity and not acceleration!
I do believe ribs can be broken!
Once I did do a karting session on a on a fast but bumpy indoor track. I new one corner could be faster ao I asked the staff. It turned out it was possible to take the corner flat out "you just need to turn off the part of your brain telling you you will crash". Well I took that corner flat out twice. The next 3 weeks were sleepless as both sides had multiple extremely bruized ribs. My doctor was amazed this was acomplished without crashing.
Interesting video! I actually get horribly motion sick and often throw up after 10 minutes of karting. Is this because of jerk? I’m fine on motorbikes so I was curious…
I have gone carting just twice and it was quite fun, despite the fact that the wheel to wheel action was pretty much non existent due to my superior speed (unlocked the more powerful kart on my first go, but even in the first one I was smashing others, probably due to better racing lines learned here) besides easy overtakes a couple times a lap. But to be fair, my perception of speed was far lower than I expected and I felt that both (14 and 17hp I think) karts were actually pretty slow.
An interesting example of how a tight circuit gives out an impression of more speed happens to two races that often take place the same weekend; Monte Carlo and the Indianapolis 500. Despite the speeds at the Indy 500 being substantially higher than Monaco, Monaco gives out the impression of speed a lot more.
Field of view and the seat of your pants.
A lot depends on what can be seen, processed and reacted to in the time you have before things go wrong. Down low with things close there isn't a lot of reaction time. It's fast because of the rate of closure on near objects.
I'm writing some simple code for a self driving toy car. I use an accelerometer and 3 ultrasonic sensors up front. The car can only see the closest thing to the left, right and center. All it does is dodge the guard rails and slow if accelerometer is unhappy but what do ya want for $50. The guard rails are just a figure eight mowed into the back lawn. It still doesn't work right but I'm close.
Hey, an old truck driver has got to do something.
Makes sense with perception. It's like it you put a camera up against the gate of a track, the cars go, vroom, but if you put the camera 15 rows back, the car goes, vrroooooooooommm. So with being farther away, it looks like it's going slower.
The last time I went karting, we had one hour of track time and I had no sore muslces afterwards whatsoever, only felt it in the ribs a little bit because I'm tiny and got shaken around in the seat quite a lot
Now don't say it was because I was driving slow, I was even almost a second per lap faster than my friend who actually owns a kart, does racing as a hobby and already knew the track... I'm also about 30kg lighter tho soooo yeeeeahh😅
remembered Senna would aggressively zig zag before coming in to the corner and you can tell from the rest of the pack . could you explain this 'bad' behavior?
shame on you unsuscribed ......shame.... shoulders forward , head down SHAME
Karting is great, I know because I'm a few hundredths away from the record in my nearest circuit which is held by a young pro. I'm 37 🙂
Low to the ground, no noise insulation or wind protection besides race clothes and helmet, no suspension meaning you feel every bump, fairly high lateral and longitudinal accelerations meaning high G forces... just off the top of my head.
Well I guess I'm a-typical then, or maybe defective.
Flying Mach Loop is kind'a boring.
I raced karts at an event with Takuma Sato at Rye House. I pushed harder and more successfully than I ever had before. However, the next day....

"How can you tell? My ass". I'm pretty sure every racecar driver has used that answer when asked questions about the sensation of speed and handling.
It's why the Aerial Atom is the best thing I've ever driven (compared to the Gallardo and 458 Spyder)
Scott, you got it wrong, mate. Check your velocity and acceleration units of measurement before asking people to subscribe.
Mr. Mansell I think you are wrong about all of this! You should fly me to England and take me to a kart track. Then we could get a couple of karts on the track and you can show me first hand.😃👍
I feel sick when I'm karting. Do you think that driving a sports car like some clio RS on a circuit would make me feel sick as well?
Such great ponts to be added as i read through.... Sounds like we got a lot more to cover 😂... I do believe it's the best way to practice rotation and being on the limit , you just cant get there realistically without some deep pockets...... But thats a good goal 🏁
having ridden motorcycles for the past 12 years, i think the exposure or danger comes into it too
while im sure that all other things being equal, things will feel faster the lower your eyes are to the ground, if you add a sports bike into the equation that gets similar increase in percieved speed to a kart while still having a fairly high eye level
it probably comes into the harshness thing but another factor is how close to the limit of whatever vehicles capabilities you are
in my car 80 vs 50 doesnt really feel any different other that how fast the scenary goes past the window, but the car will do 150 so its still barely stretching its legs at 80
The sheer number of creators using clips of the RedBull F1 drone footage proves how incredible such footage is for the sport and how powerfully it conveys the sense of the cars' actual speed.
lol imagine if we could feel the speed of earth traveling around the sun. google says that is about 67,000 MPH
Long term kart racer here (not hire karts), like any race vehicle when you get used to them they don't feel fast. These days I feel like they are slow, guess because I'm used to how they work, good kart control and used to the noise.
Answer: For the same or similar reasons a shopping cart feels terrifyingly fast when it's pulled by a car or rolling down a hill at 30 mph. 😝
this is why dang US truck drivers feel the need to go 30+ over the speed limit.... slow down and stop tailgating. if you want to feel speed get a car lower to the ground.
because you are low down, I have had the very same experience in a MIni as well
6:50 not only acceleration, but also velocity is a vector......it's not the same going 10 km/h in foward gear than it is going in reverse gear
A relative had a '79 Southwind tunnel drag boat with a 454ci and open headers. It topped out at 70 but got there in 40 feet or so. The seats were at water level. You could reach out and touch the water. That boat made you feel like you were going at light speed. I knew another guy with the same boat but blown that did 128 mph in the quarter.
Carts feel fast because your on a skate board with good tyres and a engine half the size of the bike you ride can't keep up with. And the steering wheel is the size of a orange. The latest sim wheel on Max force isn't that server.
At 4:37 I thought the horizontal line was being draw diagonally for a moment. I didn't even realize that my brain had already compensated for the slant of the horizon!
i would not have thought there are so many different perspectives on this perception
Because your arse is an inch off the ground… and as you state Driver61, your jeepers creepers are lower and working overtime.
Can't believe you talked about jerk without mentioning snap, crackle and pop.
Not too sure about that eye height, my Lexus RX SUV is 175cm tall overall and it's not a small one.
You didnt mention the "wind" that you feel when you dont have protection. I have heard of wind simulators for sim racing that uses fans to blow air at you faster as you go faster in the game to help with the perception of speed
Because your senses, located in your head, are closer to the ground.
So at a given speed, the relative motion of the road is greater.
It's just trig.
Imagine standing 2 meters away from a belt sander on its side, it's motion only takes up a few degrees of your vision.
Now have it centimeters from your face, the same speed belt traverses your entire vision in milliseconds.
i thought it was only butt-dyno (jerk) as in go cart YOU are unsprung mass :) there is much more to it
The Shinkansen (Japanese Bullet Train) has such a smooth acceleration and braking that you almost don't feel it moving
Downhill skiing also give an off this phenomenon, but to an even further extent: 70-80mph, minimal protection and since you’re on your feet and not sitting acceleration and jerk are more pronounced. Not to mention you are more exposed to the environments then in a car or kart so the mind perceives each feeling as higher.
Not to mention that I've never just flat fallen on my ass in cart. Skiing OTOH...
missed an opportunity when talking about jerk to make the joke that it's the rate at which your mates mood changes as he consumes drinks over the course of the night 🤣
The same thing happens in video games. Just changing the camera views makes you feel the speed different.
That's also relate to F1 cars generations. Because they are smaller older cars look faster even though they are slower than modern cars.
you can call Prokarts (what I race in) professional but look at one race and have another go were all dumb.
