LETTER: Speed limit shattered

Sir: "The 2005 RAC Report on Motoring found that 57 per cent of drivers break the motorway speed limit" (In Brief, 7 February). When I drive on the motorway, at 70mph, mine is usually the only car on the inside lane while everyone else zooms past. I would have estimated the number of drivers breaking the motorway speed limit to be nearer to 97 per cent than 57 per cent - or has the speed limit been increased and no one has bothered to tell me?
