Exactly! On flat roads top speed is limited by wind drag. Consider that a world class sprinter pro cyclist may be able to hit 40 mph in a sprint with a good leadout for a few seconds. A fully faired cyclist can reach 80 mph at Battle Mountain using very similar tire technology.

60 mpg hwy highest, 50+mpg lifetime
TDi=fast frugal fun
