[QUOTE="John Cone, post: 8522, member: 280"] Has anyone ever wandered, why is it when you are travelling throught roadworks on the motorways and the speed limit is 50mph that when trucks start to overtake you glance at your speedo and think mad ----ard. the answer is that truck speedos have to be re-calbrated every 2 years to a degree of + or- 2km per hour as do the Tachograph clocks which has a tolerance of + or - 1.5 minutes after 2 years. Since 1991 car speedos have been deliberatey been reading fast. The manufactures did this to prevent them being caught up in legal actions in speeding cases. At an indicated 70mph in most modern cars the true speed 67mph, at 50mph it's 48mph. Having spent some time in a past life fitting and calibrating truck speedos/tachographs i have used the equipment to test my own motocycle speedos and i can say they mostly give an overspeed reading. It's almost like the anglers tale of it was that big, or i was going that fast! [/QUOTE]
