police radar is notoriously inaccurate
I know with my boat, (and many boats) GPS is WAY more accurate than the speedometer in the dash. I imagine the same is true with automobiles. I recall an article in a car magazine a short while back where they compared actual speed (tested with what I think they call a fifth wheel) versus reported speed on the speedometer and every car was off by at least 2 MPH, some as much as 10 at high speeds!
