I generally agree but need to point out Germany is organised like the US regarding road construction. Only Autobahnen and Bundesstraßen are under federal authority, with states and municipalities divvying up the rest.
But the regulations in Germany are largely federal, no?
Same in Italy (and probably most other EU countries); there's (about 25.000km of) roads that are maintained by a state agency; others are managed by a region, a province or a city. There's also an entirely different agency that needs to take care of highways.
