High-speed roads are the most proven thing in the history of proven things - if you make them people drive on them with high speeds. For example, Germany is doing just fine with high speed roads [1]. In particular the car tires are not coming apart at all, nor does any other part of the car. Hardly a re-invention.

Everyone else was going 120mph+, and a few cars flew by me faster than I could see them, I think at least 160mph.
