Strangely more people seem to know about this than about only using the left lanes to pass. I have seen several people get worked up about being passed on the right, to which my response is "why were you driving on the left"? They don't realize that the slower vehicle chooses the overtaking lane - whichever lane they aren't occupying. In my opinion it's down to the signage: "SLOWER TRAFFIC KEEP RIGHT". Nobody wants to think of themselves as slower. Should say "LEFT LANE FOR PASSING ONLY".
