I assume that the driver of the transit/long wheel based vehicle in the last link posted is the idiot (youtube video). I can only assume that he/she looks at the speedometer after following the lorry in front because he/she isn't happy at how slow they are going. Then when the lanes split on the M25 the driver of the vehicle is allowed to overtake said lorry. After the lanes split and go from 3 lanes into 2 the van looks like he/she's having to pass people on the left hand side because they are going 'slow', this is what I assume anyway.... My only concern is that the speed limit at this point is 40 mph, no wonder he/she's clocking along like they are in a F1 car. As far as middle lane drivers are concerned, I drive like R1Geezer (although not as fast ;p), steady 70mph (min) although if I see someone approaching in my rear view mirror I will pull into the left hand lane. I always stick to the left hand lane if the road is empty but if there is a convoy of lorrys/slow moving vehicles I won't bother to move from the middle to the left lane, if I'm traveling at 70mph and someone wants to overtake me, get in the 3rd lane. Why should I make it easy for someone speeding? I bet if R1Geezer saw me in the middle lane he would do like everyone else and just pull out into the 3rd lane before I had even moved over (as a rule if i see someone gaining on me in the left hand lane I will move into it giving time for the driver to move out and overtake). On an empty motorway there is absolutely no reason to tailgate or undertake (motorways are boring, changing lanes every now and then makes it slightly less boring).
