I lived in Virginia when they instituted red light cameras. There it resulted in increased numbers of accidents when drivers panic stopped at intersections when facing a yellow light. The cameras didn't last long after that data was published. Sometimes we're already doing the best we can regarding human nature, but that doesn't stop governments at all levels wasting money trying to influence our behavior. With our Assembly, it seems they can't pass up a chance to exert more an more power over the citizenry.
