Tldr the americans interstate system is nothing more than a copy of the german autobahn... And was never something unique.

Japan eh?
The idea definitely germinated in the Autobahn. The proof is in the pudding. (I just love that expression.) The US used its scaled interstate system to achieve a range of product and population distribution that was unprecedented. It also clobbered passenger rail in the process. Conversely, Europe, not having a well developed interstate (would need to be inter-country to even scale to a few US states), did not develop or extend its road system in the way the US has. Instead, it built trains.
It's not a matter of one is better than the other. Each one is better for the countries involved because of their size and geography.
It’s even standardized: https://en.wikipedia.org/wiki/International_E-road_network
That sounds more similar to the US Numbered Highway system than it is to the Interstate Highway System: https://en.wikipedia.org/wiki/United_States_Numbered_Highway...
The Interstate Highway System is a different system - entirely controlled-access motorways, with a minimum of 4 lanes, divided, and no at-grade crossings.

If we're talking about all motorway style roads, there's some additional roads in the US that qualify: 67,353 miles or 108,394km[2].
