Plenty of people who own performance cars take them to racetracks where driving above 100mph is entirely legitimate. So doing this wouldn't affect zero legitimate use.
Not to distract from the topic but vehicles cost orders of magnitude more could be geofenced like $500 rental scooters so the engine computer would recognize the handful of high-speed tracks in the region.
How much hyperbole will we see before people realize that our entire society is built on nuanced positions? Preventing someone from driving irresponsibly is no more tyranny than saying they can’t fire a gun randomly in a neighborhood but have to go to a range.
Yes. If consumer cars’ speed was capped to 100 mph it would affect a very small percentage of people and zero legitimate use.
The difference with encryption is that while it protects criminals from the police, it also protects legitimate users from criminals.
