> They can achieve a huge safety improvement by forcing speed limit. But somehow car manufacturers don’t want to implement it. I've had multiple cars that show the current speed limit on the dash. Some based on GPS, others based on visual recognition. None of them have been correct 100% of the time. I wouldn't want my car to slow me down on a highway because it misinterprets a sign or because their data isn't up-to-date, or because the GPS is glitching and thinks I'm driving on a side road. It's a really simple solution in theory, but in practice it doesn't seem feasible yet.
