Actually from a design, construction and maintanence standpoint, our interstate highway system is nowhere near up to Autobaun specs.

OK, I'll grant that maintenance is addressed as a serious issue there and a tolerable nuisance here. My comment assumed the road was in maintained condition suitable for >100MPH driving: our freeways are much wider with broader curves and longer straight-line hauls, able to handle higher speeds easier (to the degree of being suitable for emergency landing strips, demanding a straight mile out of every 5) than the tighter tolerances of the Autobahn. Such high speeds does, however, demand greater maintenance cost and design therefor: where we just patch a crack/hole with some rammed-in asphalt, they'll take out the entire section of road and rebuild it twice as thick as we do to ensure that section is perfect as long as humanly possible.
