I lived in one city that allowed the voters to ban red light cameras, sadly I had to move to one that embraces them. One of the worst features of red light camera intersections that I rail about is the lack of countdown timers to let drivers know when the light is going to change. My firm belief is that the lack is to support revenue collection but is also to blame for many rear end collisions.
Extra short yellow lights increase revenue to the government and rear end & other accidents.
