How are you checking the real speed? Most GPS receivers display more accurate speeds than car speedometers do.

I'm assuming the GPS is accurate. I've driven through speed traps with it just on or over the limit and been fine. My car on the other hand is reporting around 5 kmh higher, depending what angle I'm holding my head at.
