I've had a long standing grudge against left lane hangers on. If your passing fine, even if you are one of those a-holes that is passing someone 1 mph faster than the car in the right lane, but the left hand lane is the passing lane and it should be enforced as so. I drive fast. Sue me. When I am going 75 mph, and I come up on some a-hole going 62 mph in the left lane, I wish to god that I had a James Bondesque missle launcher rise out of my hood and blast that slow driving jerk out of my way. There are simple rules of the road. Left=fast Right=slow.
