Again, IIRC, it is supposed to be an illegal maneuver to cruise in the far left lane. It is supposed to be for passing only. But, if someone were running my ass and he wouldn't go around me, I'd do what I could to get away from him. He said the lane was clear, so if he was running with the flow of traffic(you say you know that he was not being passed in that lane. I don't know how you know that for sure-I don't think even Google can tell you that) there is NO reason to move left to get him to go on past him. Later, QD.
