Those segment cameras are great and they made a good impact where I live. They control a school zone that up until recently has been massively disrespected by commuters trying to avoid a stoplight on the main artery.
Honestly the only cameras I really don't like are the red light cams that for some reason are also accompanied by lowering the yellow signal's time by half compared to a non-cam light controlled intersection. I'm sure there's a great reason for that happening but I can't think of anything charitable.
A lot of the cases I know about here in Ohio is they reduced the yellow time to generate more tickets. Ended up being banned state-wide because they being used for revenue generation rather than safety.
Which is obviously terrible, but that's not fundamental to the system. It would make more sense to have a state law mandating, say, a minimum yellow time for such cameras.
But when most people drive, it's easier to do something that seems very pro-driver, even if it's anti-safety.
