How about a kinetic energy limiter so if you want to drive a 9000 lb Hummer EV it’s not able to drive as fast as a 3000 lb Corolla? If I’m remembering my math right, the Corolla gets to go sqrt(3) times as fast, about 1.73x So if you limit the Corolla at say 110 mph, a Hummer would be allowed to go 64. Edit - a question for the physicists, would kinetic energy or momentum be the better metric for how deadly a projectile a vehicle is? If it’s a momentum limit then the Corolla would be allowed 3x the top speed for its 1/3 weight.
