If you're traveling down the road and you are going right at the speed limit and there is a line of cars backed up behind you and passing you at every chance take that as a clue. Move over! It's a fact. 90% of people travel 4-7 mph over the speed limit. Are they speeding? Yes. Are they breaking the law? Yes. If you want to play "traffic control" you're going to be in a ditch with a white ultra.

twoup, your are right on. Regardless of the speed get out of the passing lane if there are vehicles stacking up behind you. That lane is called a passing lane for a reason. All your doing is causing a traffic hazrd, and when your on a bike you lose. This guy was not doing it by accident either.
