Not all vehicles in North America have governors nor is it required by law.
Alot of Japanese cars do but that’s because they didn’t bother removing the governor that they use in Japan (190kph/118mph). Most American and European manufactured cars are limited by transmission or physics and not governors.
My old 90s beater had a governor at about 100mph. My current car's is 125. According to Bloomberg every car sold has a governor, but apparently I'm wrong on the reason. It's not the law but no insurance company will insure a new car that doesn't have one since the mid 90s.
That depends on the type of ebike, surely? Here in the UK/EU ebikes are limited to 250w power, motor only active when pedaling, and a max speed of 25kph. I regularly get over 25kph on my acoustic bike, should I also be banned from bike ways?
