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.
