I'm curious why you don't like the idea, because in my opinion it doesn't go far enough and should instead require active speed limitation in new vehicles (i.e. the car is prevented for exceeding the speed limit by a certain amount or at least has a much lower top speed governor). For something as regulated and potentially dangerous as driving, it seems pretty silly that cars are able to massively exceed legal speeds, particular since it's a "feature" that plenty of people take advantage of regularly with very little in the way of consequences.
