It always amuses me that people who complain of being overtaken by others breaking the speed limit, accuse these drivers of towing at "at least 70 or 80mph" How do they know how fast these alleged speedsters are going? Without actually following them and measuring their speed accurately which is impossible using a car's normal speedo, how can such wild claims be made? Anyone who sits behind a big heavy can only be doing their restricted 56mph max, although their speedo may suggest 60mph+ If anyone responds, please please keep off the dreaded and incredibly boring subject of cars with more than 2 driven wheels!
