DickyNick:
Diversion route along the A34 last week from 15 to 14, go for miles with everyone just steadily driving along at the speed limit (cars and trucks), then in my mirrors I see trucks in and out of everyone, they both come past me at must be 56 in a 50 limit 2foot away from each other. First one is yodel, second one is Hermes. I rest my case.
Sounds like the race track (A75) most days.
