  1. 23:00 The car software obviously should implement a feature that prevents the battery from going totally empty because of pressing ERS button. I would totally expect the future buyers to do the same thing even if the risk of emptying battery was mentioned in the manual somewhere.

  2.  @Keatoil  I write software for living (not car software, though) and I know perfectly well that most issues like this are caused by slight errors in the requirements for the software before the software is actually written. Hindsight is always 20/20. That said, I strongly believe that this is just a bug in the software of this car.

  3.  @VestedUTuber  Yes. However, the electric brushless motors and insanely powerful electronic motor control result in even more power to the wheels – especially because you can control electric motors much more accurate to limit tire slip.

  4. 9:00 "The badge in the front is metal because we don't use stickers or painted stuff" And then he basically describes a thing that could be equally well implemented as laser cut aluminium sticker. I guess the real intent of this badge is that the expected customer base will have a nice story to tell to their friends about the car that they purchased.

  5.  @CAPSTONE.  Tesla roadster will not do 0–60 in 1.1 sec.

  6.  @VestedUTuber  I guess I failed to communicate that my point was that nitro cars were historically the top of the line but nowadays with brushless motors and high-end ESC electric cars have taken the top performance crown. I think the switchover from nitro to electric for RC cars was near year 2013. In similar sense, I'd expect even real top fuel dragsters to be replaced with electric cars in the future. The battery tech isn't there yet, though. Full sized F1 car being nearly equal to miniature RC car is a step on this long path.

  7. They turned on low details to make sure fps doesn't drop?

  8.  @TurboGreen  Yes, the pilot uses probably 60 fps 480p analog signal for minimum latency.

  9. I would have loved to see the Valkyrie running on real slicks.

  10.  @embxssyy9936  If the car has intergrated starter motor, it might make sense to always have enough reserve to start the engine once, right? Real F1 cars do not have starter engines so there you can let the battery go totally empty because the car cannot be started standalone no matter what you do.

  11. You forgot to do brake test with 115 ton truck!

  12. It would have been more interesting to drive that S8 pass the McMurtry Spéirling at 100 km/h and then immedialy floor it and see how long it would have take for McMurtry Spéirling to pass it after starting from stand still.

  13. Just wait until they include noise regulations to "eco friendly". Then this cannot be eco friendly unless the fan is disabled.

  14.  @OnePieceSS23  Yes, but I mean that for "eco friendly" sticker I would set the max noise limit e.g. 15 dB lower than for production street ICE cars.

  15. So... Kia (with cost of 33K) did 410 km and Tesla (with cost of 48K) did 434 km. In my books, Kia wins hands down. If you don't mind the cost of the car, then there're cars with even longer range than any of these.

  16. As I like stealth, I would take S8 with A8 looks. And no low-profile tyres.

  17.  @jaychristianson  Or just youtube video compression in action...

  18. I expected Tesla to do the drag race way under 12.0 sec. In addition, I didn't BMW to have worse brakes!

  19.  @AOTanoos22  Yeah, obviously higher mass requires more braking power. However, even modern trucks have very good brakes even with 40 ton loads: https://youtu.be/ridS396W2BY I meant that I was surprised that BMW released a product which has such a long braking distance. Obviously it could be using the exact same rotors and pads as Tesla and we would see the result shown in this video. In that case, the brake hardware would be identical but the actual implementation for BMW would be worse.

  20.  @AOTanoos22  My point with truck brakes was that a truck with 20x the mass of the Tesla can brake around the same distance as Tesla (maybe 2 m more) so the extra weight of the BMW is not the cause of extra braking distance. It may have worse brakes or worse tires but either way, I was surprised to find out that they had worse braking with BMW. (This is obviously possible because the heavier vehicle has more force pressing the tires to the ground and is able to apply more force to the brakes as as a result without skidding.) I fully agree that the test shown in the video is not scientific enough to claim that BMW has poor brakes. It just shows that for these drivers and with those conditions, the BMW performed a lot worse.

  21. The difference in braking performance was surpringly huge!

  22. @Mouwcat The total amount of braking power you can have is defined by the tyre friction coefficient multiplied by the force downwards. The car with double the weight should have double the force downwards thus double the braking power if both have equally good tyres and the tyre rubber doesn't shear. That said, it might well be that in practice no rubber is strong enough to avoid shearing with double the force while still having equally good friction to the rubber that Porsche uses. (Here's a thought experiment: if you have two identical cars doing brake tests in parallel, would the brake performance suffer if you tie a rope between those cars? How about if you reduce the length of the rope until the cars nearly touch each other? Clearly it should be possible to double the weight without sacrificing the braking distance.)
