I've been known to pass them in the slow lane, get in the left lane, then lower my speed enough to force them to go in the right lane, in order for them to maintain their speed. Most of the time, I've noticed that they took the hint, at least as long as I was in their sight.
I will say that I've travelled more than a few section of interstate, in several states, where I would always try to stay in the fast lane, if not blocking faster traffic, because of the poor condition of the right lane. I don't get too bothered about that, as we ALL value the condition of our tires, wheels, and suspension.
