All people all of the time in all conditions?
No, but we want to slow people down
across the board. I acknowledge that not all speeding offences represent
equally dangerous or antisocial behaviour, but (with a very few and specific exceptions) all driving becomes
less dangerous and antisocial if slowed down. And the reason there are places where drivers who notionally agree that speeding is generally wrong still feel it is OK to speed, is that the normalisation of speeding in those places is what maintains the conditions that make it seem OK to speed. It's circular reasoning, in other words.
