Speedo error

[cml]

What ho,

Got a X300 3.2 and wondered what speedo error might be - I've been told 5 to 10% generous at higher speeds, does this sound right? So at 100 whatits per hour you are actually doing 90 to 95 whatits.

Check it with a handheld G.P.S.

By Law the speedo should NOT read UNDER your MPH or read OVER by more that 10MPH or 10%

Usually you find that they are set to read at 5MPH or 5% over




So all those do gooders in the outside lane sticking to 70MPH are infact only doing 65MPH
