I hate people that hog the outside lane (OVERTAKING LANE) too however people that undertake are just as bad and it's much more dangerous, if the dozey idiot in the overtaking lane isn't paying attention (which they clearly can't be) and finally decides to pull over at the point your undertaking then who's in the shit then? The thing that really gets my back up is when there is a que of cars sitting behind either a dozey idiot not going anywhere or someone overtaking at 1mph more than the person in the slow lane, then some idiot decides to try and undertake the whole que and cut in front just to then sit barely over the speed limit after the mobile chicane finally pulls over. I do over 400miles a week and see it all the time, the best thing to do if the idiots don't pull over is flash the lights after a mile or so and if it's goes on for a silly distance get right up their hoop - but that's still pretty silly too. I drive a bmw so effectively have a license to drive like a prick but I try to rise above it!
