I mean if your have a 750kw motor for each wheel, then they're probably always spinning when you floor it, so you also have enough torque to fully use your tires for stopping purposes

EDIT: Quick maths show that decelerating at 1g (basically what the best sport tires can do) in a 2000kg car at 300kph requires absorbing ~1500kw, so conveniently two of these motors.
