My pet hate is people in the outside lane of a dual carriageway going no quicker than those in the left lane. If you're in the right lane, over take, dont sit there like a moron.
Its especially frustrating when going over a roundabout, people exit in the right hand lane, then spend about 10 minutes sitting there before finally deciding to pull over. does my nut.
had that the other day, single lane road onto a roundabout, dual carriageway the other side for 500 yards, stuck behind some moron of a women in an Audi A2 (dreadful car, says it all really). i thought ooo great, i can despatch her and get on with my day instead of sitting behind her as if i have all the time in the world. she gets to the dual carriageway, only for her to exit in the right hand lane(why, there's no one else around!!!), and then stays there all the way to the traffic lights at the end. i nearly hit the roof! lol
shouldn't be on the road. completely oblivious to what she's doing.
