"No. All those tests are performed with high-end testing equipment such as optical accelerometer. What the car actually reads on the speedometer is irrelevant."

Exzarachy - and you'll find that that equipment that is used is horrendously expensive.
Part of the reason being that it is designed to be accurate to within probably 1/20 of 1% or less.

To make it worse, in the real world, usually these things are not a linear progression. Its more like a logarithmic or exponential scale. Twice as accurate is a *lot* more than twice as expensive, and so forth.
