Au canada, il ont ont le compteur qui va jusqu'a 300... mais pas avec 8% d'erreur...
cela ne vient donc pas du compteur en lui meme
"Well, the Canadian 0-300 speedo in my car reads a little high, but not 8%. I just went on a trip with a gps and it was maybe reading about 3mph fast. It was a pretty constant high reading as in 63mph was 60mph, 83mph was 80mph. The cruise display did show the speed almost exactly the same as the gps. When I set the cruise to read 80mph the gps showed 80mph. The error when in km is about the same, maybe 3km/h higher than what the cruise control and gps display.
The trip was through the states so I used miles most of the time.
