If you are going the normal pace in the passing lane, you are most definitely driving wrong. Get over to the right, and let faster traffic pass. If they are going too fast, let the cops take care of it.
No, it is against law in most states to impede the speed of traffic in the passing lane. The vehicle in front is not abiding the law. When he realizes someone was tailgating him, the legal thing to do is find a safe hole and merge right. Nobody, but the police should be enforcing the speed rules on the road. That is one of the many ways accidents happen- by people making up their own rules of the road.
There is usually a time component attached to tail gating. If someone is tailgating you for more than 30 seconds, that is definitely annoying. But that didn't happen in the video, did it?
How many people's lives did the brake checker endanger to prove his point? And then the coward fled the scene of the accident he caused. I'll take a tailgater on my ass any day on the road over a self righteous brake checker any day. Because I can predict what the tailgater wants- me to move over. I have no idea what self imposed rule a brake check wants out of me.
