Driving courses teach us to approach traffic lights with the intention of stopping should the signal change. If drivers run a red light and get caught by camera, they may learn from that monetary fine and become safer drivers. Logic says any deterrent is better than no deterrent. To defend against those drivers who are following too closely, just slow down when approaching an intersection.
Find the pedestrian walk lights and determine it they are blinking red or are counting down to zero, which will indicate that the signal will change shortly. These defensive driving techniques can be used whether or not the intersection has red light cameras, so you can add your own safe driving to the equation.
