If you ever wondered if your speedometer was accurate and reading the correct speed you just need to borrow a hand held GPS from someone and take a ride. I have a Garmin GPS 12 and have checked it against a certified speedo and it is perfectly accurate. If the certifed speedo said 63 mph the GPS said the same, this was for all speeds checked. Its amazing how those things work.
