I agree about bad driving. My mum and I once had an arguement in the car because some idiot stopped in front of me and a large line of traffic to let someone out at the side of the road which was just inconsiderate, then straight after at the next traffic light stopped dead even though our filter light was green. I honked and my mum said I was being rude and maybe the other person isn't a very confident driver. She couldn't see my point that driving is not a game and if you can't drive properly you shouldn't be on the road.
Anyway in regards to middle lane driving, I thought the police were given new powers to pull people over and fine them for poor lane discipline on the motorway? I mean these t*ssers who obliviously sit in the middle lane are effectively turning a 3 lane road into a 2 lane road, causing congestion and putting other drivers who have to change lanes around them at risk. (The worst are the ones that sit in the 3rd lane on the 4 lane stretches of the M1 - every time I drive to my parents house in Leeds from the big smoke I always see a few. Honestly makes me want to put my window down and scream at them for their inconsideration and stupidity.)
