Basically none of them are good enough for a real world scenario in a busy city. But they may save life on some scenarios which is good. They can achieve a hug

  > But somehow car manufacturers don’t want to implement it. Maybe because nobody would buy a car that enforces its idea of the current speed limit on the driver? (It'd be good to have as an option though, I agree, as long as it can be overridden.)

  > Basically none of them are good enough for a real world scenario in a busy city So what's "good enough"? Even if these systems don't prevent all collisions they'll often vastly reduce the speeds at which they happen.

  > 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.

  Not exactlty the same thing, but Volvo has stated they plan to limit the top speed of all their cars to 180km/h
