I do a quite a bit of night driving. I'm always in the right hand lane on three lane roads. Night traffic is very light, so I won't change two lanes just to go around people that insist on driving in the middle lane when the right lane is empty.
1 and 2) So everyone should have to change lanes to get around you, but you shouldn't have to change lanes for anything?
3) Typical 3 lane highways have 4 actual lanes, the right most one being the breakdown lanes and can be used in an emergency. That means being in the middle lane gives you one lane to your left and two to your right, vs. one to your right and two to your left. Same difference, no added benefit.
I think that's what he meant.
