Speaking from germany, 33 in a 30 wouldn't even trip the speed cams here. Earliest infraction is basically doing 6mph over on a 30mph road, which would come at 50€ fine. We apparently also have 50 times less speed cameras and it absolutely does not stop people from fucking malding over them. They have to be designed bulletproof here now and even those still get regularly blown up. None of the points you raise change anything about it, because the core issue is people are terminally car brained
