Had one of those come tear arsing past me in the 3rd lane of the M40 N/B or E/B whichever way you want to call it on the drop down to Warrick services as I was overtaking a Co-Op waggon 
even on the level section of the motorway he was still well over 56mph and Iād hazard a guess even doing over 60mph the way he shot off into the distance.
