I agree absolutely that no-one should be penalised for falling asleep in a motorway service area and overstaying their 'Welcome Break’. The practice of setting a time limit for parking and then imposing a fine was introduced, presumably, to stop drivers leaving their cars parked for an exceptionally long time. The only reasons I can think of for doing this would be either to dump a car, or to car-share. Leaving aside dumping and car-sharing over a holiday - which could be identified after 24 hours - what is wrong with car-sharing during a working day? Surely it is something that should be encouraged? It uses less fuel and means fewer cars on the road.
