You don't need experts, you need only proffesional equipement. Reporters from car magazines do tests all the time. I remember some of german big test where noone car showed no real speed! Some of theme made mistakes for more then 20km/h! Bigger speed. No one shows less.
The problem from the car speedometer, you are right 100%.
