It is not the law, the law does not forbid an accurate speedometer, which is not difficult to implement particularly with modern motor vehicle design. The difference in tire radius from wear is trivial as well. There is a big difference of 1% accuracy and 10% plus 4 (imagine... you are seeing 200 km/h on clock and going only 178?!). Even 5% (test above) on a $60 000 car or whatever is unacceptable.
