This is actually a problem in the area this article is from. In maryland the yellow light is much shorter then in virginia, therefore maryland drivers tend to stop at yellow lights in virginia which causes lots of close stopping of drivers behind . If safety was really a concern then there would be a more narrower range of allowed yellow light duration between counties and states. As far as the speed cameras are concerned they only reduce speed for a very short distance once everyone knows where they are, its a pure profit motive.
Seems like VA drivers should stop racing yellow lights, and should maintain safe following distance. Even if the driver ahead chooses to roll into a stop at a green light, drivers behind should be able to stop safely.
