It's just a cat & mouse game anyway. If the government didn't want people speeding they would regulate the max speed of new vehicles to be 70mph off the show room floor with built in shut down for tampering with the car.

I read an article a few years back in Car & Driver about Arizona and it's running the read light cameras. It's all about the $$$, and a little safer roads. They actually moved the sensor further into the intersection so that if the light turned red, they had a better chance of getting a picture of you passing through the intersection. They basically took away the "commited to the intersection" gap.
A little something from another website related to Mesa, Arizona.
