What's intimidating about that? If the car ahead of me is getting further away (ie, going faster than me) then I move over so that those behind me can go as fast as the car in front. That's not selfish. If the car in front of you is going slower than you, then you can move to the left, just move back right to clear the lane [strike]if there are faster people behind you.[/strike]
Driving slower than the people behind you want to and refusing to acknowledge they are there by moving over a lane is selfish, in my book. Not recognizing that there are other people on the road is selfish.
Agreed, with a modification. No need to wait until there's people coming up behind you, just move over to the right if it's clear. The left lane is for passing, if there's no one near you in the right lane then you're not passing... So get the eff back to the right before you're blocking the left lane for someone else.
