He got confused turning into a canyon, thinking it had an exit to a lake, but it was a box. He tried to navigate his way out of it, doing a 180, but couldn't climb high enough, fast enough, and crashed on the bank of the other side.

@@Hachiae I agree. Car companies show their vehicles drifting corners and speeding through mountain trails. Doesn't mean I should try it. Hell, Suzuki sponsors Travis Pastrana. Maybe I'll try a double backflip.

To add to what I said.. you never get in a vehicle where the driver/pilot takes off thinking there's a 100% chance you'll be parking safely. Never. That's called ignorance.
I’m a real life pilot and wow, there’s no doubt that an AoA indicator in GA planes would have done work a lot easier, even to understand how important it is to interpret correctly and knowing it’s limits with a little simple and complex instrument at the same time.
In June 2015, the company indicated that they had 1,250 orders for the A5 and plans to build 500 per year by 2017. Total number built by the end of 2017? 23. Total number built by 2019? 90. Meanwhile, the price is up to $400k. Hmm...
Thanks for the stats. More Icons are in the news and why? They're crashing from either sport pilots taking risks from unfamiliarity with the range of issues related to water takeoffs and landings coupled with low time experience to ignoring medical risks from drugs affecting dynamic effects from flight.
I looked at becoming involved in the company when they first started prototyping. The issue I recognized, and one that troubled me, was their incredibly top heavy corporate structure. Never a good thing when you are trying to develop a new product and input from the design floor is important.
Team Synergy congratulates Icon for putting AoA awareness front and center and for bringing it to the forefront of the aviation safety discussion. What a nice priority to insist upon from your earliest designs forward.
The gauge might be misleading. I might be flying at very low airspeed, yet be in the green since I'm descending and thus be unaware that pulling up even slightly would immediately land me in the red. I think airspeed is also important since you've got to have either kinetic or potential energy to play with. If you've got neither, you are either touching down or about to crash.
Weiwu Zhang Stall angle of attack (critical AoA) does depend on Reynolds number, but in the context of this aircraft (small speed range, low altitudes, etc.) I would imagine that critical AoA is considered a constant value. The gauge is directly reading AoA, and thus the reading is relevant in all scenarios. Stall speed (in IAS), not stalling angle, is affected by bank angle. But yes of course knowing your airspeed in addition to AoA is important since those two things determine your rate of climb (or descent).
When descending you will generally still be pulling 1G. Stall speed is unaffected by whether you are ascending or descending, you are just more likely to end up in a stall ascending because you lose speed faster. Sub 1G loads are impossible to sustain for long (the ground objects), and will not affect your airspeed the way high G loads will. The cool thing about AoA is that it is pretty linear. If you are pulling 1G at a certain AoA you will pull 2G if you double the AoA. That means that if the guage is in the green you have a lot of lift available to you. Pulling back on the stick will not make you stall (though you might lose speed fast). Definitely agree that speed is life, altitude is life insurance, but these are more medium term heuristics compared to the immediate "wings produce lift and drag based on AoA" concerns.
no, the only way to be in the green with very low airspeed is with less than 1G flight, not possible for long as others have commented. assuming constant AoA for stall is a good enough method for practical concerns. in general critical AoA changes with airspeed (well actually reynolds number, but all factors other than velocity in reynolds number is constant) but the change is very small and assumed constant above a certain threshold, for most applications in aircraft reynolds number is very high and not considered a factor in AoA. i agree with the icon designers in that it should be included in some way shape or form in every airplane, particularly GA planes as they are flown by less experienced pilots.
ICON is a great small aircraft company in California, Not many left here. I own a small manufacturing business and have done some work for them, The people there are Top notch to work with. Have not heard much from them as of late, but am looking forward to possibly working with them more in the future. Not many innovative small business left in this state compared to 20-30 years ago. Go ICON!
After flying around in a lot of GA planes I have to say AoA is something I wish I had from the beginning. I'm not a private pilot or LSA pilot but I have friends that let me fly with them and perform landings and such. With AoA I could see myself nailing perfect landings every time.
OK, I admit it. I'm impressed. I've been a fan of Advanced Flight Systems' AoA displays for years (still am), but that's about as intuitive a display as one can get.
Yep it is a pretty representation of the old buzzer that has been around for decades. I can still hear the buzzer starting to come on in my head as I was doing stall / spin training. Buzzes a little you feel it getting mushy it buzzes a lot in a turn you are going to have fun ! Correct me if I'm wrong but I don't see this as being revolutionary.
My thoughts exactly! The stall horn is an AoA indicator... just simpler and cheaper, and at least you don't have to see it to be warned. In most practical ways, the old stall horn is better.
Another excellent addition to the A5 project. Kirk, I have said it before, I'll say it again, outstanding team, outstanding accomplishments. Look forward to touching base at Osh and congratulations on the AoA accomplishment a beautiful pairing with the spin recovery and BSR systems. Win, win, win.

WOW! Now I know what that indicator is on the dashboard of the ICON A5 in MSFS. I've been wondering since I first tried it a few days ago. Logged in 9 hours of flying on the ICON A5. Thank you!
After having a difficult time flying the other planes in Flight Simulator 2020 I hopped into this thing and had a blast, even if it's a video game its angle of attack gauge is so intuitive to fly. I was like landing on lakes and making low height maneuvers it was like a duck
The problem with removing all those buttons and making this appear to fly so easily is novice pilots and the general public will believe they don't have to follow basic flight safety in order to be in the air.
While not critical for GA aircraft (afterall, GA aircraft have been flying without it) an AOA indicator would be VERY helpful. It would give you a graphic representation of would you are on the speed/loading curve. To say that a pilot would ignore his VSI because of the AOA indicator is like saying that he would ignore his VSI because of his airspeed indicator. You use the available instruments to get a picture of what teh aircraft is doing.
Wow, I'm impressed! I would really be impressed if they ever sell an aircraft. The only thing they've sold so far is stock in their company and a promise. Both of them have the same value.
Brilliant idea! AoA has been a thing of Business Jets upwards for far too long! Really important piece of information. I'm sure it will be integrated into Garmin / Bendix / Avidyne suites before too long!
It was never clear to me how it came to the point where pilots are thought to fly airspeed and not AoA. You can stall wing at any speed. AoA is what makes ti stall. Still a lot of pilots have the idea that you fly slow you stall, fly fast you are safe, and that is absolutely wrong. So cudos to you guys doing the right thing,
Absolutely! AOA is the most primary information needed by a pilot. Archaic FAA regulations requiring Airspeed, etc. (and not AOA) exist only as an artifact of history -- from the 1920's! It's time for a change. FAA needs to dispense with the requirement for Airspeed, and add a requirement for AOA.
@@josiahR125 That is not fixed until they have three redundant sensors instead of the single sensor the cheapskates have fitted right now. Those new huge engines have shifted centres of pressure so far that the plane is almost unflyable. I will never travel on one.
My issue is you could buy two ultra modern STOL Zlin cub ultras with the turbocharged rotax 915 , one on floats and one on wheels for the price of one of these .. Two brand new far more capable planes for the price of one
It calculates the angle of attack. It tells you which way the wind is moving across the wing and calculates when the wing will stall based on the airspeed. So if you bank 90 degrees to the right and pull hard, the indicator will move toward the red and determine if you're going to stall in your turn. An artificial horizon would just tilt and show that you are banking. This tells you if you're going to stall in your turn, climb, dive, or level flight. It doesn't just show the aircraft's position based on the horizon.
AoA is the angle between the chord line and the relative wind. The artificial horizon shows the angle between the planes current pitch or attitude to the horizon.
I feel for these people and the families of those who have gone. I have seen new and old pilot's who needed to go back to school. The ground/water is not your friend, it is there waiting to kill you. An engineer who I work with bent two Harvard's while training in the Airforce. Staying alive and safe is a mindset. I have spent years climbing in canyons/kloofs, no one in their right mind wants to fly any kind of aircraft in these places. I nearly bought the 'Farm' a few years ago. It was in a B747-400 over central Africa. We went through some really severe thunderstorms. We dropped tail first out of one of them. Then hit the updraft, this was like hitting a wall. I never thought you could corkscrew one of these things, but we did. The pilots had to hand fly us back to France for repairs. Thanks for the interesting video, this thing is like a flying Jetski on Testosterone. And greetings from Africa.
Once again must I be surprised that the Icon team have incorporated in the cockpit of the A5 and Angle of Attack dial? No! I am not, because these guys do know what it takes to fly aeroplanes. My faith only grows stronger from drawing board to full production of this craft.
RE: (`Its an AoA gauge, its been in experimental aircraft for over 15 years`) Who says it`s not ? and of course it`s been around for ages,but to have it incorporated in a light aircraft is a quite a new development.Once again Well done Icon to the Icon team and designers.
An interesting note from the pilot's handbook reads: "If the engine quits in instrument conditions (blind flying when you can't see the ground) or at night, the pilot should pull the control column full aft (it won't stall) and keep the wings level. The leading-edge slats will snap out at about 40 mph (64 km/h), and when the airplane slows to a forward speed of about 25 mph [40 km/h], the airplane will sink at about a parachute descent rate until the aircraft hits the ground."
Simultaneously the antithesis, and yet the epitome of good old fashioned stick and rudder flying. High tech yet simple. Lol. Mixed feelings. I came here because I love aviation and aerospace, have played several sims, and just got Microsoft Flight Simulator as my new go to sim. I tried the A5 and excuse my french, but in the parlance of our times, I thought to myself, "Wtf is this gimmicky sh!t doing in the introduction to bushcraft section lmao." That said, I really really love it. Really, AoA is a really key metric to think of when you're flying, even though most planes aren't outfitted with a guage and you're just estimating or guessing it. I've only ever had it displayed somewhere for me (cockpit guage or otherwise) in a military sim. I don't like the idea of pushing it as the be all end all, let people hyperfocus on this one metric and not really learn my IAS, bank, rotations at each altitude etc. A large fraction of Alaskan bushcraft pilots fly unlicensed... Not saying they should, but it's the reality we live in and it's not my place to judge anyway. I've seen estimates that say anywhere from 5 percent to 45, anyone's guess really unless you have a really well-funded study that'll never happen. I wonder what prices and accessibility of aircraft with AoA guages and cockpits like this will be like in 15 years from now. I know y'all say you're working on bringing affordability up, or were 8 years ago at least. Anywho, cool stuff, it's a really fun guage to fly, get some more performance out of the craft, and a really great safety feature. I'm just hesitant with it being so big in front of me and my traditional 6 pack being less prominent/somewhat hidden.
The AoA system is a result of the pilot’s flying, not the other way around. Making corrections based on it is like resolving the effect of a problem instead of the problem.
I love this plane it’s a brilliant piece of engineering, its biggest problem is it’s been marketed wrong right from the beginning and has more or less killed this project.
What will kill this plane in the market is price. A cute plane, but not $389K cute. An AOA indicator is a great idea. Why not retrofit to your current aircraft?
the AOA indicator is revolutionary for general aviation. I'm sure we'll see more of it from other manufacturers. There needs to be a standard, though. Same gauge, same lines, like that.
does the parachute get caught in the propeller when activated? would be interesting to see worst case scenario procedures in real time as they are a security barrier for most people considering flight.
Also, stall angle of attack may be different at different conditions: altitude, humidity, leading edge surface finish, Reynolds #, side slide, and other. It would be more accurate to use stall indicator based on something else (like airfoil surface pressure, or so) instead of the angle of attack. Practically, it may be a condition that it stalls even AoA indicator says it should not. So you will need to icrease safety margin to compensate errors.
F-16 has an angle of attack indicator just to the left of the hud. Monitoring it to maintain 11 degrees aoa is a large part of the landing procedure. Another cool fact. F-22 and f-35 can fly in excess of 50 degrees aoa.
Aerospace Engineering Student and Multimedia Graduate here. In regards to UX, wouldn't a gauge that starts flat (Horizontal) at zero AoA and also displays negative AoA be more intuitive as well as more quickly inform the pilot?
My dad had one in his Bonanza in the '90s, a prototype he and an electrical engineer friend of his had developed and tried (unsuccesfully) to sell. Not nearly as slick as Icon's (just a row of green/amber/red LEDs) but was nifty :)
It's good and would be useful. A very easy to interpret AOA gauuge has been in existence for a long time. It is found in USAF T-38s. Besides the guage, there is a 3 light vertical display that sits in your line of sight on top of the glare shield. A red chevron points downward if you are slow, a green donut in the middle if you are on speed, and a yellow chevron pointing up if you are fast. we "fly the green donut" ...
I like the idea of Alpha as primary instrumentation, but noticeably absent is a vertical speed indicator. You are building a seaplane that potentially will need to execute a glassy water landing. With no reference on when to flare, the only way to land is to set up a pitch-power combo that will result in a constant vertical velocity around 150-200 ft/min. This pitch-power combination changes with density altitude, and must be established at a safe altitude and checked with the VVI, before landing. Without a vertical velocity instrument, how do you propose a potential customer perform a glassy water landing?
One question! Can you put this AoA piece of technology or device in other planes too? And will it work as effectively as it did here? Something like a Cirrus S22T 2020?
Actually, how would the AoA indicator respond to a slip? Say left turn base to final, too high. Left wing gives what, 20% lift, right way less, no lifting body. So the plane is in a controlled rapid descent without laminar airflow disruption, unless the SHTF very quick as any of the problematic factors are factored in when used by an inexperienced pilot. Thanks in advance for an answer... Bueheller?
Having been a Wing Public Affairs Officer in the Civil Air Patrol I would like to know what rating is required to fly this airplane. Experience doesn't seem to be a issue.
what about the feddback from the joystick ? AoA is it advisable because the joystick feedback (pull push stress ) is very light or because the inside of the cockpit is such that we can't rely on "visual references" into icon ?
Stall speed is all about the airflow over the wings. If you are in an envelope which reduces the airflow then you will stall. Where that envelope is depends on many factors, but AOA is one of the biggest factors. Wing loading is another. Wing loading might be the biggest contributor to stall speed. It will determine your effective AOA. The AOA is controlled by the pilot. Wing loading is a manufacturing concern. I hear about the "spin resistant" wing, but I wonder if that comes with a price of raising the wing loading? I am a part 107 pilot, but I also build scale aircraft and wing loading is one of the biggest factor when choosing an airframe. Park flyers have super low wing loading, and so they can fly low and slow, but the EDF jets usually have higher wing loading, so you can get more lift at the higher speeds. Scale usually sits in the middle depending on what you are building.

My issue is you could buy two ultra modern STOL Zlin cub ultras with the turbocharged rotax 915 , one on floats and one on wheels for the price of one of these .. Two brand new far more capable planes for the price of one
"we just need another, oh, let's say" $80 million to make this work... "

C'mon guys! I can't wait any more, I want to fly it!
Is this not just an artificial horizon or am I missing something?
It calculates the angle of attack. It tells you which way the wind is moving across the wing and calculates when the wing will stall based on the airspeed. So if you bank 90 degrees to the right and pull hard, the indicator will move toward the red and determine if you're going to stall in your turn. An artificial horizon would just tilt and show that you are banking. This tells you if you're going to stall in your turn, climb, dive, or level flight. It doesn't just show the aircraft's position based on the horizon.
AoA is the angle between the chord line and the relative wind. The artificial horizon shows the angle between the planes current pitch or attitude to the horizon.
I feel for these people and the families of those who have gone. I have seen new and old pilot's who needed to go back to school. The ground/water is not your friend, it is there waiting to kill you. An engineer who I work with bent two Harvard's while training in the Airforce. Staying alive and safe is a mindset. I have spent years climbing in canyons/kloofs, no one in their right mind wants to fly any kind of aircraft in these places. I nearly bought the 'Farm' a few years ago. It was in a B747-400 over central Africa. We went through some really severe thunderstorms. We dropped tail first out of one of them. Then hit the updraft, this was like hitting a wall. I never thought you could corkscrew one of these things, but we did. The pilots had to hand fly us back to France for repairs. Thanks for the interesting video, this thing is like a flying Jetski on Testosterone. And greetings from Africa.
Wow, this machine looks like incredible fun and AOA is balls....
Once again must I be surprised that the Icon team have incorporated in the cockpit of the A5 and Angle of Attack dial? No! I am not, because these guys do know what it takes to fly aeroplanes. My faith only grows stronger from drawing board to full production of this craft.
Love those camera angles of the A/C in this video!
I have fallen in love with it. in fact, I'm inspired. Someday, I will have it.
Kage Krôss nnn
Why couldn’t airspeed, wind, humidity, etc be computed with a variable AoA into one display, with standard gauges in blackout?
Also add audible warning
A child could fly this puppy! AOA indicator that demonstrates optimum approach vector? I want!!!
RE: (`Its an AoA gauge, its been in experimental aircraft for over 15 years`) Who says it`s not ? and of course it`s been around for ages,but to have it incorporated in a light aircraft is a quite a new development.Once again Well done Icon to the Icon team and designers.
An Angle of Attack indicator: I wish I had this when I was learning to fly all those years ago!
Im getting a private pilots license and icon says it gives its own aircrafts with sport pilot license, can I still get the icon with a private?
An interesting note from the pilot's handbook reads: "If the engine quits in instrument conditions (blind flying when you can't see the ground) or at night, the pilot should pull the control column full aft (it won't stall) and keep the wings level. The leading-edge slats will snap out at about 40 mph (64 km/h), and when the airplane slows to a forward speed of about 25 mph [40 km/h], the airplane will sink at about a parachute descent rate until the aircraft hits the ground."
Simultaneously the antithesis, and yet the epitome of good old fashioned stick and rudder flying. High tech yet simple. Lol. Mixed feelings.
I came here because I love aviation and aerospace, have played several sims, and just got Microsoft Flight Simulator as my new go to sim. I tried the A5 and excuse my french, but in the parlance of our times, I thought to myself, "Wtf is this gimmicky sh!t doing in the introduction to bushcraft section lmao."
That said, I really really love it. Really, AoA is a really key metric to think of when you're flying, even though most planes aren't outfitted with a guage and you're just estimating or guessing it. I've only ever had it displayed somewhere for me (cockpit guage or otherwise) in a military sim.
I don't like the idea of pushing it as the be all end all, let people hyperfocus on this one metric and not really learn my IAS, bank, rotations at each altitude etc. A large fraction of Alaskan bushcraft pilots fly unlicensed... Not saying they should, but it's the reality we live in and it's not my place to judge anyway. I've seen estimates that say anywhere from 5 percent to 45, anyone's guess really unless you have a really well-funded study that'll never happen. I wonder what prices and accessibility of aircraft with AoA guages and cockpits like this will be like in 15 years from now. I know y'all say you're working on bringing affordability up, or were 8 years ago at least.
Anywho, cool stuff, it's a really fun guage to fly, get some more performance out of the craft, and a really great safety feature. I'm just hesitant with it being so big in front of me and my traditional 6 pack being less prominent/somewhat hidden.
I will have one delivered as soon as it downloads
The AoA system is a result of the pilot’s flying, not the other way around. Making corrections based on it is like resolving the effect of a problem instead of the problem.
Power or airspeed is critical to aircraft's stall characteristic. Leading edge flaps or slots can help prevent it but power is still needed
I love this plane it’s a brilliant piece of engineering, its biggest problem is it’s been marketed wrong right from the beginning and has more or less killed this project.
What will kill this plane in the market is price. A cute plane, but not $389K cute.
An AOA indicator is a great idea. Why not retrofit to your current aircraft?
have you thought about the mvp it would be nice to be able to loose that wind screen after landing
Yeah, the wing loading on those suckers is enormous!
the AOA indicator is revolutionary for general aviation. I'm sure we'll see more of it from other manufacturers. There needs to be a standard, though. Same gauge, same lines, like that.
this thing is soooo handy, I'm not a pilot but I've been playing flight sim with this little bad boy and damn its nice to fly.
does the parachute get caught in the propeller when activated? would be interesting to see worst case scenario procedures in real time as they are a security barrier for most people considering flight.
Also, stall angle of attack may be different at different conditions: altitude, humidity, leading edge surface finish, Reynolds #, side slide, and other. It would be more accurate to use stall indicator based on something else (like airfoil surface pressure, or so) instead of the angle of attack. Practically, it may be a condition that it stalls even AoA indicator says it should not. So you will need to icrease safety margin to compensate errors.
F-16 has an angle of attack indicator just to the left of the hud. Monitoring it to maintain 11 degrees aoa is a large part of the landing procedure. Another cool fact. F-22 and f-35 can fly in excess of 50 degrees aoa.
I don't care what fancy system you have, Flying close to the ground/water is never safe.
hello And most aircraft land on land. The point is, unless you’re landing, altitude is your friend.
@@RandomNumber141 As my flight instructor used to say: the only altitude you have to worry is the one below you
I'd love to fly this airplane... need to save a few more pennies until they opportunity arises. awesome work.
2:27 i didn’t know billy bob Thornton switched gears to become an engineer
Lmao
Isnt this what adjusting your trim accounts for..?
adjust trim simply counteracts the nose up or nose down tendencies of an aircraft.
Aerospace Engineering Student and Multimedia Graduate here. In regards to UX, wouldn't a gauge that starts flat (Horizontal) at zero AoA and also displays negative AoA be more intuitive as well as more quickly inform the pilot?
I'd love to have an AOA gauge in the airplane I fly.
My dad had one in his Bonanza in the '90s, a prototype he and an electrical engineer friend of his had developed and tried (unsuccesfully) to sell. Not nearly as slick as Icon's (just a row of green/amber/red LEDs) but was nifty :)
So the wing articulates during flight???
How did they find out where to place the red line? also what kind of sensor does it use? is it a weather vane on a stick in front of the plane?
Does it take normal gas
Yavy Sanchez yes, it takes 95 octane motor gas or 100ll Aviation gas.
wrong.... 95 octane isn't normal gas found at your local gas station where I live!
@@danailcenco7567 It actually takes 91.
how are you measuring aoa over the wing? pitot tubes?
Was alot of this shot in tehachapi California?
Does it have a Vertical Speed Indicator?
Really cool plane guys, but where can I go with a 20 gallon tank?
Any plans for a 4 seat variant of this aircraft?
I want to buy it, how long is the waiting list?
Practical - Yes
More reliable than the airspeed? Not really sure
The physics says yes, provided their sensor works. Low speeds don't cause stalls, high AoA does.
It's good and would be useful. A very easy to interpret AOA gauuge has been in existence for a long time. It is found in USAF T-38s. Besides the guage, there is a 3 light vertical display that sits in your line of sight on top of the glare shield. A red chevron points downward if you are slow, a green donut in the middle if you are on speed, and a yellow chevron pointing up if you are fast. we "fly the green donut" ...
I like the idea of Alpha as primary instrumentation, but noticeably absent is a vertical speed indicator. You are building a seaplane that potentially will need to execute a glassy water landing. With no reference on when to flare, the only way to land is to set up a pitch-power combo that will result in a constant vertical velocity around 150-200 ft/min.
This pitch-power combination changes with density altitude, and must be established at a safe altitude and checked with the VVI, before landing.
Without a vertical velocity instrument, how do you propose a potential customer perform a glassy water landing?
i feel like this will be a game changer
Continue with the excellent work. You guys rock.
4:05 that was so satisfying to watch
Excellent idea.We should use AOA in the liners as well!
Fabio
One question! Can you put this AoA piece of technology or device in other planes too? And will it work as effectively as it did here? Something like a Cirrus S22T 2020?
Another wonderful Feature on Icon A5.
Actually, how would the AoA indicator respond to a slip? Say left turn base to final, too high. Left wing gives what, 20% lift, right way less, no lifting body. So the plane is in a controlled rapid descent without laminar airflow disruption, unless the SHTF very quick as any of the problematic factors are factored in when used by an inexperienced pilot. Thanks in advance for an answer... Bueheller?
Having been a Wing Public Affairs Officer in the Civil Air Patrol I would like to know what rating is required to fly this airplane. Experience doesn't seem to be a issue.
what about the feddback from the joystick ? AoA is it advisable because the joystick feedback (pull push stress ) is very light or because the inside of the cockpit is such that we can't rely on "visual references" into icon ?
+T PR There is buffeting as you approach the stall, so you get plenty of warning.
Stall speed is all about the airflow over the wings. If you are in an envelope which reduces the airflow then you will stall. Where that envelope is depends on many factors, but AOA is one of the biggest factors. Wing loading is another. Wing loading might be the biggest contributor to stall speed. It will determine your effective AOA. The AOA is controlled by the pilot. Wing loading is a manufacturing concern. I hear about the "spin resistant" wing, but I wonder if that comes with a price of raising the wing loading? I am a part 107 pilot, but I also build scale aircraft and wing loading is one of the biggest factor when choosing an airframe. Park flyers have super low wing loading, and so they can fly low and slow, but the EDF jets usually have higher wing loading, so you can get more lift at the higher speeds. Scale usually sits in the middle depending on what you are building.
Does it make a noise when you stall ? Also how much does this aircraft cost ?
Very well done, Icon. More active safety means less passive safety, and with this kind of marketing there will be more crashs.
