well I hate to say it...........but I agree with mk2vr6 on this one... :) Anyhow I thought.. Lane 1 ( outside lane....as its on the outside ? )....this is for slow sensibly driven vehicles. Lane 2 ( middle lane ).....Women and Old Men (possibly trying to achieve 60mpg )....or to pass slower vehicles in lane 1. Lane 3 ( inside lane ? ) .....only to be used for overtaking slower vehicles in the lane 2. NOTE: vehicles made by BMW & Mercedes are not alowed in lane 1 or 2 except in the first 10 metres when joining or leaving the motorway.
