Most automated camera tickets for buses, red lights, or speeding only result in municipal fines and no insurance complications. The camera can reliably get the lisence plate but the tech and bureaucracy isn't ready to prove who was driving each car.

Apparently, the issue with mail-in tickets specifically is that while the camera can catch the license plate number, it can't really prove who was driving the car. So whereas an in-person ticket from a cop for passing a school bus will result in points on your license, a mail-in ticket from a camera like this won't. The same problem applies to people that just don't pay the mail-in tickets - the state doesn't really know who to go after specifically.
