There are lots of ICE vehicles that have enough power to overcome their brakes My diesel pickup could easily rip the brakes to shreds under acceleration. Electric vehicles are known for crazy amounts of torque as well… sounds like somehow this guy had both the accelerator and the brake pedals depressed at once. It’s weird

> There are lots of ICE vehicles that have enough power to overcome their brakes My diesel pickup could easily rip the brakes to shreds under acceleration. I'll dispute that. Have you actually tried that? If so, your brakes are defective. There's an easy intuitive way to visualize this. Remember that any change in speed or direction is acceleration. Braking is just acceleration with a negative sign. The engine generates horsepower to accelerate the car from zero to some speed. While we don't usually speak of HP when talking about brakes, it is equivalent. We can also compute how many HP the brakes are producing when accelerating (with a negative sign) the car from that speed down to zero. So: a car that has a more powerful engine than brakes would be able to accelerate from 0 to 60 (or pick some speed) faster than the time it takes to brake from 60 to zero. Can you think of any car or truck that can accelerate faster than it can brake? Doubt it (unless the brakes are broken). To your truck example, I have a one-ton turbo diesel truck. I hadn't tried this experiment so was curious after your comment and went for a drive. As I expected, if I hold down the brakes the truck won't budge even at full throttle. The brakes are massively more powerful than the engine. They have to be, after all those brakes are designed to bring the full rated capacity of the truck and trailer (28,000lb) to a stop from highway speeds. The engine, while very powerful, has way less power (acceleration potential) than the brakes.
