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

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

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

  4.  @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.

  5.  @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.
