Sat Navs v. Speedos

Sat navs are a far better indicator of speed than a speedometer, the whole raisond'etre of a sat nav is to know exactly where you are on the planet which it plots loads of times per second, therefore can easily compute your exact speed. Whereas a speedometer has to rely too many variants such as tyre circumference, gearbox wear, mechanical wear etc. etc.

I've been using fuelly.com to keep a track of my campervan economy since I got it:



Pretty happy with that, so far.

speedos are always set to over read a little , so if you are doing 80Km /hr it should read , say , 85

so if the sat nav say you are going faster than the speedo is reading , you have a problem somewhere ...I have no idea whether or not sat nav's tell the truth or not
