I disagree. If your at the speed limit and unable to move over then to hell with the guy behind. He has no right to get past you and you have no obligation to let him.
When people do that to me, I slow down more. And if I really take a disliking to the idiot, then when he pulls out to get past me, I speed up so he can't
EDIT: Lol, I didn't realise the post I was responding too was 2 years old! I voted manual anyway. Automatics are boring.
That is really a jerky thing to do. And two wrongs do not make a right. I hate driving behind people who will not pull over especially when I lived in TX and driving on the shoulder was legal. In many states you must pull over if you have a certain number of cars behind you regardless of your speed. This is b/c it is obviously dangerous if somebody is being a pain in the but and making a bunch of cars behind all try to jockey for position to pass.
