I knew the GPS were way off as my previous Navman was spot on compared to the cars speedo, but the TomTom is way off the mark. So I don't trust either! It's only an indicated speed, not actual speed, so we can only go by what is shown with its +/- tolerance.
I took this photo on the M25 on the way home (sort of) from the MGCC annual meet at Silverstone in 2003. This is the stretch of motorway between the A1 and the A1000 (Potters Bar). A major incident occurred at the Holmesdale Tunnel junction, so the police turned us all around (eventually) to take us up the down ramp at the A1. I was actually only doing around 50mph when I took the photograph.
