So no reaction time, huh? I'm glad your car has the yellow detector that automatically applies instant braking.

Civil engineers run the numbers. When the camera company gets involved, those numbers get thrown away to make more revenue. (In fact, sometimes the camera company's contract actually defines the maximum yellow time the city is allowed to set.)
