F1 pundits never tire of telling us that the downforce of a grand prix car is so strong that they could drive upside down on the ceiling without falling off. Well, on behalf of the Mayor of Birmingham, I would like to invite Bernie Ecclestone to hold an upside-down Formula 1 race on the underside of Spaghetti Junction. It would add another dimension to this sport and a bit of overhead excitement to anyone stuck in traffic on the M6.
