IMO stop light cameras are solely about revenue generation and not about safety.
I agree with you 100%. Ironically, one point of this article is that the REMOVAL of red light cameras will ultimately be driven by revenue generation (or lack thereof), too!
Obviously there are people for whom a yellow light means to floor it. The camera industry has financial incentive to hand out more tickets. Most Americans hate traffic cameras IMHO because they are un-American. We do not trust our govt officials or the companies making money off the tickets.
