Was overtaking on the middle lane last week, while being overtaken on the outside lane which is normal motorway traffic. Two lorries on my left had a bit of a gap between them, not much point fitting in there and just to proceed on at 70 and slot in when it gets clearer. All of a sudden some pillock flew past behind on my left into the gap then pulled out in front of me and zoomed off. Those 'speeding' on my right where obviously too slow. While I've never seen the outside lane "sunday drivers", too bloody many of them in the middle lane.
