Do you know how we determined the accuracy of our speedometers in each everyone's car (different make). A simple method we always do. Drive and run in a convoy with only one takes the lead of the speed. The leader may run and maintain speed at 80kph and will not exceed. As we drove in convoy, ( in an expressway ) we glance and look at our speedometer points at that very same speed mark (80kph). It's fun, as we do it every year in a family field trip, or summer outing.

Let say 6 vehicles with different car makes, we all run at a speed of 80kph. All 5 vehicle match in each speedometer gauge, while the remaining 1, his gauge reads at 65kph while we are all running at the same speed. That means his speedometer gauge is out of specs calibration or faulty.
