That's why they threw them out in Hawaii...
There were white vans parked alongside the road, they were private hired by the City and County of Honolulu, therefore, it was a money thing. Anyone going over the speed limit got a ticket. There were lots of folks going 2 or 3 miles over the limit that got tickets in morning and evening rush hour traffic who showed up in court... The judges threw out everything 6 mph and under, also threw out a lot more in questionable cases. No more speed cams. BIG public outcry.

Red light cameras are a bit different, but barely, because it's still big brother. Plano, a bit above Dallas has a lot of them. That seems to stop folks running red lights, also traffic accidents at those lights decreased about 2/3's. I think the newspaper said they threw out about 1/3 of the tickets before they were ever sent... as in yellow is ok, but red was not.
