Drove back to the Midlands from Gloucestershire last night. Arriving at the (finally finished - thank heavens) 4-lane section on the M5 which is controlled by ATM's sorry... "speed enforcement" cameras I did as usual and set the cruise control and resigned myself to relative "crawling" on a three-quarters empty motorway. Lanes 1 and 2 were totally empty so I moved over to the left and sat at the legal limit in Lane 1. In lane 3 about 150 yards ahead there was a VW driving at the same "legal" speed... it sat there like a moronic robot for at least/over ten miles at the same speed while the other lanes stayed empty. It's such a nonsense - 120mph would have been quite safe especially if people used the marked grrr! lanes correctly. There was of course, no plod around. So much for enforcement of lane discipline... but if I had speeded up in a camera section, the postman would be bringing me a present today! I really pity those who were going further north - the elevated section leading up the M6 still has that dreadful section with a 30mph limit and distance cameras (oh, and nobody working - ever as far as I can see)!
