My girlfriend got a "camera" ticket a few years ago. It had her picture, very clearly driving her car. She paid the fine, which was about eighty bucks I think. They have since removed most, if not all of these devices from highways in our state (Arizona).
Funny, but true story about this subject. Several years ago, a brand new freeway loop was built around Phoenix. Loop 202 was three or four lanes each direction with wide sweeping curves. When the Loop was first completed they installed speed sensing cameras at several locations. Speeding ticket was a flat $75.00 for each infraction, so guys with really fast cars would go out there middle of the night when there was no traffic and see who could generate the highest official speed (certified by Arizona Departmant of Public Safety) complete with official speed and a picture of the car. These guys would gladly pay the 75 bucks, do more tuning or modifying and go out there again to make another run. The state finally wised up and began a new fine structure, instead of 75 bucks for each infraction, the next ticket was $150, then $300, then $600, etc., etc. These cameras have also now been removed too . . .
