On a 3+ lane (in one direction), I don't really care so much, as long as there is a path threw the idiots. In fact I like the right lane so I can see up on-ramps in my side mirror.
On 2 or 1 lane in each direction, I am a bit more militant except on 80 over the pass where the right lane sucks. If I am forced to go around the right because somebody won't move over, I will often make a point of moving in front of them after the pass; not too close, but quick enough to remind them that somebody else is on the road. They often get the hint and move over.
Nothing pisses me off more than people who do not use turnouts on 1 lane (each direction) roads. With most of the passing lanes having been removed over the years due to idiots failing passes and getting in accidents, I am flashing lights well before each turnout, and if you don't use it, you get the horn on the next one, or first one if long enough. I wish this was enforced more.
