What if to brake safely you come to a stop over the line? (large truck behind you or someone riding your ass, speeding etc?)
If someone rear-ends you, then that's their fault. 100% of the time. They were following you too close or not paying attention. You can only control one thing when you are driving--yourself. Stop staring in your rearview mirror when you are driving. You only need to look into it when you are going to make a lane change, or if you hear sirens. I rearended someone myself--going 50mph--because I was looking in my rearview mirror too long while doing a lane change, and they were stopped dead on the highway.
On the other hand, stop lights should have the timing set correctly--that is, they should stay yellow long enough for someone going the speed limit to either make it through the intersection, or to stop prior to the intersection. But the article is not about red light cameras, it's about speed cameras.
