Well, my only experience with someone getting what was coming to them was a driver who was tailgating several other drivers, and passing in no passing areas while using a delightful hand gesture and honking his horn.
The road is one lane each way, with hilly terrain and curves that make it difficult to know when traffic is coming the other way. Therefore, there are no passing zones for at least a five mile stretch. Also, there are a half dozen locations where law enforcement likes to hide and wait for people who speed, since the speed limit is very low. Those of us who drive this stretch every day know we just have to obey the limit and be patient, because the officers are real sticklers for the posted limits. Five over will get you a ticket, unlike in most places, due to the hazardous conditions.
So this driver gets behind me just as we start going around a really sharp curve in the road, blinking his headlights at me and getting so close that sometimes I can’t see the headlights anymore. We are about one mile from where the road conditions improve and the speed goes up. I continue driving the limit, and try to ignore him. He tries to pass once, but a car comes over the hill ahead of us, and he has to get back behind me. Once that car clears, he pulls out and accelerates rapidly, well over the limit, to pass me. Just as he gets right next to my car and gives me the delightful gesture and honks, I notice the officer parked on the side watching the whole thing. On go the lights, and he gets pulled over. The rest of us passed him by as he got his ticket.
If he had waited less than a minute, he would have been able to pass legally in an area with a higher speed limit.
So I have to think that people get what they give. We may not always see them get it, and it may not change their behavior, but they get what is coming to them.
