Have you considered...
"Driving is a multi-task activity that requires concentration at all times. Drivers have to pay attention to a number of operational and environmental factors."
The fact that the number of rear-end collisions increased when red-light cameras were installed exposes poor driving skills, not some problem with drivers suddenly aware they need to practice increased vigilance about the lights.
As someone said above: driving to closely to the car in front of you increases the risk for a rear-end collision, not the presence of a camera.
As to whether they shortened the yellow-light duration when they installed the camera as a deliberate revenue-raising scheme: easy to find out. Time it with other light where no camera has been installed. If the duration is shorter, call city hall and give 'em curry about it.
