Indeed. My weak Google-fu indicates that the coefficient of friction of tyres against a dry road surface is something like 0.9, so there must be some improvement in tyre technology here just to make the thing go without creating a thick black smelly line on the road.

A car doesn't drag along the road. The tyres are in relatively static contact (unless you're drifting etc.). Static and dynamic friction are quite different.
