Cars usually have both at the same time. I rarely use it but I can see the appeal of a speed limiter for people who don't pay much attention to their speed but just want to be sure they don't get flashed by a speed cam.
Is this outside of NA? I've never seen this feature in the US.
I have seen them on BMWs. Quite fun, you can put pedal to the metal but the car wouldn't go above what you set the limit to. It certainly helped while cruising Munich in a DriveNow (car-sharing service) BMW.
This is a feature that (coming from Europe) I've missed when driving in the US. I didn't know that it was generally unavailable, I thought I had bad luck with my rental cars.
I don't think it's an option except in special cases or on company vehicles and large transport trucks
After 3 speed traps you'd loose your locense in France. License costs around 1k€, that's why the speed limiter is probably popular in France
I have both on my European Ford, not used the limiter though.
