@fullselfcontrol The story seems to check out. The original video published by the driver is here: https://youtu.be/0BTrEt6scwQ

3:10 I think F1 rules should be changed to be absolutely clear if you're supposed to leave room for the other car or not. If the rule is considered to mean that you have to leave space for the outside car, the move Max did here is definitely not okay. However, if the rule is that you don't need to leave space for the outside car, I agree that as long as the inside car stays within the track limits it's clean move. There should also be clear rule that if the inside car goes outside the track limits, it shall get 5 second penalty, no questions asked. It has seemed to be that the stewards cannot decide which rule they follow here and as a result we get incident after incident because drivers cannot agree on the rule either.
48
He obviously had nothing else to do while waiting for wheels to touch ground again.
46
@Cheeky_Goose I agree. The correct way to combat "stealing IP" this way is to have long enough non-competitive clause in the contract. However, that gets really expensive really fast and its the reason it is not used more often and instead companies go to court to try to handle these cases.
22
Are you going to publish cost estimates for building the "tunnel"?
12
I think 11g would be doable but it would need computer assisted launch control because you couldn't accurately control the clutch under 11g acceleration. Again, doable but not allowed under the current rules.

@ramosel If FIA really wanted to cut costs, they would specify the metals allowed for gearbox and the engine. Allow only specific grades of steel, aluminium, copper and brass and engines and gearboxes just got a lot cheaper and if you keep the requirement to use the same engine for multiple races, the teams would be forced to use stronger gears.
6
@seanwolinsky9306 I agree that Masi's offer was great for the Red Bull but if we want Max to stop driving recklessly the stewards just need to be throwing 5 sec penalties for every incident until Max starts to stay within track limits. As such, I think Red Bull shouldn't have been offered any leaway here by offering swapping positions to skip penalty.
6
@KepleroGT Good question. I would say that the reason is the cars need some minimum width to include the human driver. And if you want to go fast through the corners on wheels with human passanger, the wider you can make that car the faster you can go. And note that even superbikes require almost similar width because they need space for the human to tilt sideways even thought the part that touches the ground is really small. Wider track allows selecting from multiple options to execute a turn, the narrower the track is, the higher the probability that all the acceptable driving lines go through one car width position on the track.
6
5:00 I didn't know that F1 gearboxes had such a cassette system for taking the gears out of the gearbox. Sure makes replacing the gears a lot simpler than fidling with the parts inside the housing. The fasteners that hold the cassette on place were also surprisingly little considering how much power F1 cars have and when you have wheel hop with those sticky tires, the forces the gearbox sees are insane.
5
Not broken at launch? As in "it's a polished release"? Sure, it doesn't constantly totally crash (the software, not the car).
4
I agree with your reasoning that it would have been best if Hamilton had left no room at all when he was ahead. If official rules do not allow that even though drivers actually do that and in fact it would have been the safer way to execute this corner, the rules should be fixed. That said, I do think that Max had a bit more fault in this crash but maybe the fault was 70% Max, 30% Lewis which I would still consider as pure racing incident. Another video asked a good question: how many percent it must be your fault to no longer be a racing incident? 51%? 90%? 99%? I think I would draw the line around 90% mark.
3
That's my thinking too, it would make sense to have pressure operated switch inside the wrench socket and the wrench only activates when enough pressure is detected (say, 20N). This would require the wrench operator to just hold the trigger while pressing the gun towards the nut and when pressed hard enough, it takes off the nut. And if the slots do not engage, you couldn't apply the 20N pressure no matter how much you press.
3
If rules had such a requirement written in clear way, we wouldn't be having this discussion. I must wonder if the current rule is intentionally vague as even wording of your your comment here would be clear enough without multiple paragraphs of text.
3
@RedCardinalLP I agree on the history of the ruling. However, the F1 is not about gentlemen racing as a hobby but top level pros doing it for living. And then good drivers will go at the borders of rules to extract any little extra gain they can get. And when borders are not clearly set, we get a mess.
3
It nicely demonstrated how rigid the helmet is. Until the last little bit was cut the helmet wasn't already warped away. If that was made out of plastic like some cheap helmets it would have been nearly melting near the end of the cut and pieces would have fallen away from each other long before.
2
@duckmucker Obviously you should use gloves designed for angle grinder work. It's true that incorrect gear may be more dangerous than not wearing anything.
2
I think Verstappen should have been punished for defending by going off the track limits. If this is allowed in future, too, one can always defend by taking inside and intentionally releasing the brake pressure to block the outside line and going off the track limits while still blocking the outside car. I'm pretty sure that FIA is not going to allow overtaking by the outside car running off the track limits because that would be major safety issue.
2
Yes, sequential gearbox is pretty simple and robust but it's hugely expensive to manufacture. That's why pretty much no road car has one.
2
@ChrisColyard Drivers have to press a button for DRS. I once thought that there was radio control for areas where the button press actually did anything but I might have understood that part incorrectly. I nowadays think that the drivers can press the DRS button anywhere but using it outside official zones results in penalty.
2
@wody21 It seems to me that the current rules are not clear enough to make clear decision when you have to leave room for the other car and when you can select the ideal line. There were many incidents about this over year 2021.
2
@petersizen3897 I agree. Human reaction time is about 100 ms and you can easily tap faster with your foot. As a result, you can tap the gas pedal faster than you can think so you should press it hard to test grip limit but you have to release the gas until your human brain can process the results 100 ms later in case the grip was lost immediately and the car would be going sideways before you can even figure it out.
2
The race would have ended with the order under safety car and Lewis would have won the championship by running to the finish behind the safety car. Masi just decided that he didn't like that so he bended the rules because "race" was more important than following the written rules.
2
The full video can be seen at https://youtu.be/cxDz0Z066NI - the image quality is pretty poor because that's from 1983. Note the gear stick and I think those cars didn't have power steering either.
2
I think new cars will be more edgy. Those new cars will have really high grip most of the time but will lose grip suddenly when going over suitable series of bumps. The new tires will make the car even more snappy which will make this even worse. That said, I think this is good for the series because the limit is hard to find and if you overstep, the car will be out of track. That means that you can improve speed with pushing the car more but if you push too much, you don't get any warning before the car is out of the track. I would guess that means that you can overtake more with high risk but that obviously comes with high risk for the overtaker. The interesting part will be how stewards rule the not-so-clean overtakes and overtake attemps. I really wish the rules would be made more explicit and less grey areas.
2
@jean-jacqueslavigne3109 Great info! Thanks for sharing details.
2
I think all the info included was good. A better software to draw over the video and faster movement from frame to frame during pause would shorten the video without sacrificing information.
2
@killhour And many older cars with ESP setup have real brakes with vacuum booster (instead of brake-by-wire) and those have binary switches in pedal for the brake light but pressure sensors in the pipes to allow the computer to implement the stability control.
2
@tomasgamboa3164 If two cars enter a corner side by side and the car inside goes out of track on the outside, it should be automatic penalty every time. Otherwise you can always defend overtaking by running inside line to corners and braking straight out of track limits; the car next to you cannot turn on corner because it would collide with your car and if you go outside the track limits, they cannot overtake either because there's zero track remaining.
2
Does the ackerman setup change according to suspension travel? I think it would make sense to somewhat increase amount of negative ackerman when the outside suspension is more heavily compressed and reduce it when the inside suspension is compressed (such as when going over the curbs).
2
@ejv0wjc08gtsnoj0 I think it's called bump steer only when executed badly and the suspension causes the car to over-react to any bumps.
2
Great analysis! There were some audio/video sync problems in this video, though. It seems like the audio of you speaking wasn't correctly syncronized with the video of you.

@lucamendes5755 According to FIA pages (which I would assume are trustworthy for this) F2 cars have 755 kg overall weight and 620 HP @ 8750 rpm. https://www.fiaformula2.com/About/14LCsEEMG9yyx5DkhcN1J8/the-car-and-engine-f2 And the F3 cars have 380 HP @ 8000 rpm: https://www.fiaformula3.com/About/5tGE8Qr5FdTJJwaUN0YbWq/the-car-and-engine-f3
2
TL;DR: weight distribution and the fact that (racing) cars have better brakes than the engine so it makes sense to get on the throttle earlier which means you should try to rotate the car earlier in the corner.
2
Interesting project for sure! Funding the project is going to be the hard part because the structure you need to build is basically single-purpose single-use thing. And the car you're using is not an actual F1 car so it cannot be a marketing stunt for F1 series either. Typically I would guess Red Bull for this kind of stuff but I think this is going to be too expensive even for their marketing department.
2
Yes, even if you trust the driver, any mechanical failure will get you hit by about 700 kg doing 80 km/h.
2
5:20 I think the rules should be written to either explicitly allow or disallow this move. I'd prefer this being automatic 5 sec penalty for the inside car but not everybody agrees. I'd actually prefer having the driver getting 5 sec penalty for every time he or she goes off the track limits. That would make the track limits much more important (similar to tracks where gravel starts at the track limit) and still much safer than having gravel or grass next to the limit. If there were no exceptions for the 5 sec penalty, drivers would take less risk. If you could force opponent to go over the track limits (without violating rules) and get him or her to receive a 5 sec penalty, that would be a great move, too. That said, you're fully correct with the ending of the video that if nobody takes any risks the racing will be much more boring.
1
@misme2000 If drivers knew they'll get automatic 5 sec penalty for going off the track limits, you can be sure no driver would go over the limits 30+ times in a single race or they definitely deserve that ~2.5 minute penalty.
1
@tonlit4640 They already have cameras for every corner. And stewards don't even need to monitor the camera feeds during the race. Other teams will be willing to do that for them. All that's needed is ability to rewind and play to inspect footage of claimed incidents. NFL has allowed video checks for quite some time, surely F1 can allow the same. F1 cars are not going so fast that simple video wouldn't be enough to tell if the car did stay within the track limits or not.
1
This new Ferrari has curves that put top models to shadows. And the paint job with semigloss finish looks awesome – it will be interesting to see if the real race cars have similar finish or smooth mirror like surface.
1
Great project for the students! And now they can do multi-year project to build even faster car. If the real target is education and you produce a quickest car as a side-product in 3 years, it's still worth doing. When students do it as part of their education and the project is split into small enough parts that each individual student does only a small part, the overall cost is still acceptable because students do not get salary for their work. And if you produce even faster car in 3 years, that's a superb ad for your educational program.
1
I think the most important part is that oversteer camp needs car setup where the transition from traction to sliding is as smooth as possible. If the traction is lost without a warning, it will be too hard to drive fast no matter how much skill you have. Human reaction time is the limiting factor.
1
Once you use jet engines or rockets, it just plane or rocket that's steered with a wheel (maybe). It seems that this car has vertical stabilizer so it might be steered similar to airplanes, not like cars. I would want to see similar video about fastest car that uses only rotating wheels to pick up speed.
1
What was the small part on top linking the left and right rear suspension? Is it some kind of torsion bar to prevent body rotation?
1
I'm afraid that nothing will happen and rules stay as messy as they are. Maybe they change some wording so the rules are different kind of messy... I hope they change the rules so that race director cannot walk over the rules anymore. I'd prefer red flagging the race a more often situation. that would gather all the cars in a group, allow everybody to change tires and let the race continue from the next lap. Safety car is only needed if you must fit the race length in given time slot or cannot have enough tires to keep swapping tires on red flag situations. Of course, it would also be interesting if they cannot use any more tires because they had already used all the tires despite the red flag. If you want more actual racing on the track, red flag and restart from the grid seems like a good solution after any incident that cannot be handled by just yellow flags.

It seems that the actual cause was that Colin had expired helicopter licence, he was lacking type rating (official training for specific helicopter type) and he was doing some kind of stunt flying with the helicopter during the time of crash. "Trying to fly in a valley at relatively low height and high speed was a "demanding manoeuvre", the AAIB said. "The pilot placed his helicopter in a situation in which there was greatly reduced margin for error, or opportunity to deal with an unexpected event."" "The report said that McRae's five-year flying licence had expired in February 2005 and he was also not authorised to fly the type of helicopter he was operating, because his "valid type rating" had expired in March 2007. There had been several cases between 2004 and the time of the accident of "non-compliance with existing regulations", and the AAIB added that McRae would have known his type rating had expired when he flew from Scotland to London in March 2006, since the purpose of the flight was to meet with an examiner to renew it." Source: Guardian: "McRae did not have valid pilot licence at time of fatal helicopter crash" Some say that he ignored "don't cut" instructions while flying.
1
@gravyboat2370 The actual cause of the accident is unknown. It's known (from publicly undisclosed video) that Colin was flying really low in a valley and he was either doing high g turns in horizontal or vertical direction. Some wording made it appear that the crash may have caused by trying too high g turn near the woods and the helicopter just couldn't take make the turn and it crashed into trees. That helicopter didn't have "black box" to record the actual accident so nobody knows the exact details.
1
Good job for Aston Martin figuring this out. I totally expect next year rules to simply increase the minimum radius so much that this design is no longer beneficial but would be technically allowed (with bigger radius, of course).
1
It's all nice and fun until you look at the leaderboard for the whole world and find you that you're still 30 seconds too slow.
1
100% agreed.
1
They would need to make this track much wider or all the F1 cars are going to drive on the same line meaning no overtakes.
1
@MultiArrie I'm pretty sure you can create tracks that have fastest single car wide racing line with side effects. For example, the fastest racing line could cause heavy tire wear whereas e.g. going slightly higher on the ramp could be slightly slower but reduce tire wear a lot. In such case, over a long race you cannot always go for the fastest option which would help with overtaking.
1
@1crazypj Nobody wants straight cut gears in normal road cars due the noise. And for only 4-6 gears creating a non-sequential gearbox saves about 4-6 gears. If sequential gearbox was actually cheaper to make, VW and Toyota sure have resources to make those boxes in mass production instead of their non-sequential stuff. When I wrote "hugely expensive" I meant the current situation. "More expensive" would explain the reason why those are not mass produced for road cars. I would estimate that sequential gearbox would be 150-200% of the cost of non-sequential gearbox for road cars if it was mass produced.
1
I'd argue that you can go way past 21000 RPM if you truly want but you wouldn't get more power per engine cc because of compromises you would have to do for a gasoline engine. However, if you run nitromethane such as RC cars, you could easily run engine up to 50000 RPM. Of course, at those RPMs you would get better economy with a helicopter style gas turbine engine if you have enough money to get one of those. ...and your racing regulations allow you to uses non-internal combustion engine.

Congrats on your wedding but unfortunately I cannot help with subscriber count because I've been a subscriber for a long time already.
1
I would say it was seat of the pants traction control system. I think it disturbed the balance of the whole car and he used it to check both the traction of the rear wheels and the front wheels. That said, I think it caused more wear to tires and as those are intentionally inferior today, this technique wouldn't be good for F1 driving where taking care of the tires is nearly the most important thing in fast racing.
1
I think the next season of "Drive to survive" must start with "based on a true story" or viewers will say the story is not believable.
1
@_F_rog If they can do 700 meter long steel structure with safety critical parts for only a couple of million, that's cheap!
1
@bideomanlol The F1 cars use collapsing tanks to avoid fuel sloshing around in the corners inside the tank. Could ethanol vapors cause enough pressure to prevent the tank from collapsing when fuel gets low? If the fuel sloshes around in the corners, the fule could easily be cut from the engine given the high sideways g forces that F1 cars can generate.

@jean-jacqueslavigne3109 methanol is not allowed in F1.
1
@jean-jacqueslavigne3109 Maybe that's April fool's joke? I cannot find anything else about F1 and "binex".

For road cars, the spring where the coil has different strength for diffent parts (usually implemented with non-equal rise per turn) is usually called progressive springs in marketing material. It's much better than regular spring but more expensive to manufacture.
1
Kalle Rovanperä did something similar in Porsche Benelux series a couple of weeks ago. Kalle has two WRC Rally1 championships so he can obviously drive cars fast but Porsche Benelux series is about every driver having identical car and very minimal adjustments allowed and no ABS, TC or stability control to aid the driver. And still Kalle was able to win 4th race he attended and he set the P1 in qualification for 3rd and 4th race. And you have to remember that this 24 year old driver had rally experience which requires very different driving technique compared to circuit racing.
1
@Hole_Motorsports If you look at the video around 7:30 mark you'll notice that there was already a catch fence. The question is, what if the tire (separated from the wheel!) bounces and goes above the catch fence?
1
@tomasgamboa3164 Yes, I'm giving an option how I think the rules should be laid out to allow fair racing. Why do you think you have any authority to say who can speak and who cannot?
1
@tomasgamboa3164 It seems to me that you're jumping to conclusions pretty fast. Perhaps there's some kind of language barrier between us? English is not my native language so it's totally possible that I explained the situation poorly. To give a concrete example, let's take 90 degree turn to left. Cars A and B are running side by side before the corner, A on the left. My point is that if you allow A to run up to 2 tires over the outside track limit (the usual limit for track racing as far as I know), there's no way for B to overtake A. This is because A can always start to brake so that he or she could be take the line next to apex preventing overtake via inside. However, during the braking A can see how B is behaving. If B brakes hard, A does so, too, and can position his or her car next to B preventing overtake. On the other hand, if B tries to overtake by going outside, A just releases the brakes somewhat and runs up to outside track limit with B alongside which forces B to basically stop or run out of track limits. Do you understand the case I'm talking about? Do you think B can overtake at all if A behaves like I explained?
1
@nearlyretired7005 Adding points to license for every time you go outside the track limits might be a good solution. Obviously, if you DNF there's no need to give out penalty points because we're only talking about going off the limits to improve performance. That would allow keeping the safest possible track (gravel reduces your ability to brake before barrier a lot!) and still gives a real incentive to avoid going off the limits.
1
@studlydudly Exactly this! The F1 regulation has been changed a lot and the modern regulation is more gimmicky: bans on changing car mechanically, requirement to use at least two different tyre compounds during the race even if it slows you down, requirement to use intentionally inferior tyres (the tyre manufacturers are required to manufacture soft rubber that must destroy itself in few laps no matter how much you baby the tyres), very very strict restrictions on aerodynamic surfaces of the car etc etc. F1 cars had to run the whole race on single set of tyres in 2005 but somehow we should think that after 20 years of additional research, modern tyres should only last a few laps?
1
@kspectre21 I guess it depends on what you consider "good enough". For me, a single crash a day is borderline acceptable, RAM or VRAM leaks are not acceptable at all and sudden latency spikes that destroy minimim FPS are not acceptable. That's minimum bar for an acceptable release. Then we can debate e.g. if the simulation is realistic enough for collisions or tarmac or gravel.
1
Great video! I hope you could get Jimmy Broadbent to drive F1 car as well because that would be insanely good collab.
1
Great video but I wish you stopped using clickbait titles. For example, this could have used title "Why F1 Banned this GENIUS Device: MGU-H" to avoid clickbait title and similar naming could be used for the whole series of videos about banned technology.
1
This is like bridge engineering: what's the weakest structure you can build that still accomplishes the task?
1
@ejv0wjc08gtsnoj0 Exactly. Modern multilink suspension (especially rear and it started with Ford Focus in the 2000's, I believe) steers the wheel according to the compression and if you modify springs, you should readjust the whole geometry. It also means that even a small problem with the spring will misalign your wheel geometry, too. However, when everything is adjusted correctly, the end result is that the car feels like going on the rails around the corners even when there's bumps on the road.
1
8:25 Wait a sec! Why cheap EV cars are not already using these motors? 3 kg per wheel would be acceptable unsprung mass for a road car and 4x 67 hp would be plenty enough for a typical family car. You could have 4WD + torque vectoring and skip the diff and cvt joints and lots of other parts, too.
1
9:00 Oh, the regulations have a HUGE loophole when engines are not included in the budget cap.
1
Lots of interesting details in this video! Are you going to do a video about all the changes needed to the ICE engine to be able to do this?
1
@amazingblyatman5760 For me the only bad part of the modern F1 cars is the tires. Year 2020 version was already bad with intentionally inferior tires that FIA requires go bad after a couple of laps instead of being the best the tire manufacturer could do. Year 2022 version with bigger wheels / lower profile tires is going to be even worse. Consider year 2005. The race length was the same and they weren't allowed to change tires during the race and the tires were still in pretty good condition at the end of the race. Modern tires explode after 30 laps.
1
Great video! I would have preferred water jet cutting for even cleaner cut and less dust. How much did that helmet weight before cutting?
1
I think the regulations should be changed to allow engine software to be modified at all times the car is not on the track. That means it could be modified for qualifying and during every pit stop the race day, too. That would allow more strategy options for the teams during the race, too. The Mercedes party mode that allowed the driver to adjust engine parameters during a single lap was a bit too much in my opinion.
1
Is there some reason torsion bars are not used in normal road cars? The suspension takes a LOT of room in normal road cars and torsion bars would allow much more interior space especially at the back of the road car. Do these wear a lot quicker, for example?
1
We haven't yet seen Russel with too many cars but from what I've seen this far, it appears that he is really fast to adapt to different cars. Ricciardo appears to be the other way around – he wants that the car is adapted to his style and if that cannot be done, the results are poor.
1
I think the biggest thing that should be fixed is the max width of the car. Reduce it by 20-30 cm and it would be much better. Everything else is less important. The reason every team is going to always build up to max width allowed is that with human driver, the cockpit always has some minimum size and minimum center of gravity. And to get that center of gravity through corners faster, you want to put the wheels as far away from the driver (sideways) as possible.
1
@simonwadd4038 Yeah, and I've later found out that the wheel guns are standardized / regulated, too, so if the gun doesn't have such feature it cannot be added by the team either.
1
So basically compared to normal manual transmission car, this has much smaller diameter discs, much stronger springs, uses titanium instead of steel everywhere and friction material is fully made out of carbon. And because the springs are so hard, the hydraulic system is run by the engine, instead of simple pedal connection as in normal cars. And most normal cars have just one friction disc and this has three. But other than that, it's exactly like the clutch in a Ford Mondeo with manual transmission.
1
Delta wings are used in supersonic planes because it's needed to combat some issues with supersonic airflow. Having delta wing shape for anything that goes slower than the speed of sound is more like a marketing trick instead of required for aerodynamics.
1
I wish modern F1 were continuum for this kind of racing: very little rules and let teams innovate. Right now F1 has truly insane amount of regulation. It would be much better to have teams freely innovate but to keep costs low, the team would be forced to sell the car after race for $1M. That way you wouldn't want to use insanely expensive materials and competitors could also see all your tricks after purchasing the car. You would need to constantly innovate if you wanted to have edge over competition.
1
2:30 Also imagine the forces on your hands without powersteering and hitting a pothole while landing a big jump.
1
Could you do video about how modern cars implement the adjustable suspension dampening because they no longer can put the dampener inside the coil spring to save space?
1
The problem is that rules are not clear enough so the stewards seem to decide practically randomly if the moves Verstappen does are legal or not.
1
@royd7760 This season was definitely something else. I've often written that if "Drive to Survive" was fictional series, it would be told to be too irrational for this season.
