I would also like to understand why the most basic regulations aren't in place on cars to limit their maximum speed, and maximum acceleration and/or power?
It seems like the general public all agrees that it would be insane to allow arbitrarily powerful e-bikes, and so they are limited to (depending on your jurisdiction) 500 watts and 32km/h. This, despite that there are nearly 0 deaths from e-bikes per year. Cars and motorcycles on the other hand, are orders of magnitude more dangerous and we have no restrictions whatsoever. There are street-legal cars with 1000 horsepower and top speeds of over 400km/h.
