Yeah but then they will give you more points for having an inaccurate speedo lol. Theyre not too bad at lower speeds, i think the gernal rule on saxo speedos is 1mph out for every 10mph so its like 10=9, 20=18 and so on.
I know 35 is about 30. And ive been pulled for not doing the speedlimit in a 50, my dials said 50 but apparently i wasnt doing the speed limit
