If I recall correctly, you weren't there. How do you know if he couldn't get over to the right? You don't. If the lane was clear on the left, then yes, move over there long enough for him to get around you and then get back over. I'm not arguing that you should be in the far left(that's actually something you said that made sense). He's trying to get out of some idiot's way. You are still an idiot if you actually think that "there is no reason to ever move over left." Later, QD.
