> we also have hatching cameras (yellow hatched boxes mean no stopping, usually at junctions)
Weirdly I've never encountered these in the US (only red light cameras) and do we ever need them. I'm generally opposed to government associated cameras due to concerns about turnkey authoritarianism but if we have to have cameras at intersections they could at least curb the awful self centered behavior.
Most states ban speed cameras and many ban red light cameras as 4th amendment violations. You cannot face your accuser when your accuser is a robot. As a result, speed camera tickets have always used some legal sleight-of-hand to nail you into confessing, and this has become unpalatable.
If we raised speed limits (almost) across the board to the actual safe limits of modern cars, I think a lot more people would be ok with speed cameras. There would still be a constitutional problem, however.
