Drove up from Oxfordshire to Cheshire yesterday - M40, M42 and M6. Obviously, on the motorway one should keep left unless overtaking other traffic.
However, on a "smart" motorway, if they've got the speed limits set down to (say) 40, does keeping left really matter? If all three or four lanes are moving along at the speed set on the gantries (and doing more than that gets you a ticket), is there as much need to keep left?
Yesterday on the M6, several people seemed determined to get past at 50 and get themselves busted by the cameras, and very cross that I wasn't always bothering to keep left. Am I wrong?
