Drop in red light tickets and rear end collisions

It's like I always tell people about Photo enforcement cameras is that if the amber time is under what is allowable by law.Then you don't have enough time to stop with out triggering off the flash that takes the picture of your plate. like I seen in an article on the National Motorist Association blog is that in Corpus Christi last year when the increased the amber by three quarters of a second a forty percent decrease in rear end collisions will follow as well as less tickets.
