In Washington State, it is illegal to drive in the left lane on a highway except to pass. They don't enforce it much, but I do know people that have been pulled over for that reason (albeit let off with warnings). As a result, it tends to be the faster lane to travel in. Unfortunately, this isn't the case for all states.
