its very rare a a car speedometer is correct , they have a variation of accuracy
According to various sources I looked at for this video car speedometers are accurate within a few percentage points of actual speed. So in the test when we drove 60mph the car would be accurate within 0.6 to 1.8mph. Even with that inaccuracy we were still able to test acceleration pretty good.
