Thread: Check your speedos.

Every car i have owned has been about 10% out.
To get a ticket for over 105 have to be going close to 120 indicated on the spedo

Ah. but is it 10% out at all speeds, such as 20 30 50?.............Is it doing 10 whilst parked in your garage?

I notice on a lot ofo the Youtube videos a stopped vehicle (equipped with a GPS system) often show it as moving ....sometimes up to 5.

At first i thought that might have something to do with the earth's rotation but then realised that the satellite the GPS was using, is in an unchanging, fixed, stationary point to the earth

54/55kmh on radar signs and gps when 60kmh on the spedo. ~100kmh when 110km on the spedo.

Its definitely %. Its not constantly out by 10kmh
