This would prevent speeding (but stop overtaking) on motorways, which I argue are the roads that need the least speed control. Speeding is probably more harmful on all other roads where you have pedestrians, cyclists and complex road layouts.

I agree, but if the goal is to simply stop speeding, it will stop it on motorways. Whether it has any safety benefits or not is incidental.

Oh sorry - to be clear, I was being a little pedantic about he question the parent mentioned - what is his solution to stopping speeding. I agree that reducing Speed limits (particularly on motorways) isn’t the answer. There are other reasons for it however, eg Ireland [0] is attempting to reduce the speed for environmental reasons.
