It may be 'within 10%', but it CANNOT read less than your actual speed.
So the makers build a level of error into the system. My LR4 was 3kph+3% over about 60 kph. Below that it was spot on. VW are about 5%, but they used to give a way of showing the actual speed through a hack of the climate control. Audi are about 3%.
I truly hate those people who consider themselves traffic cops, and drive in the right hand lane of freeways, generally at exactly 105 kph. Your speedo might say 110 kph, but all the rest of us see is a mobile road block.
