Public transportation is on a different level and all mayor cities are connected via a high speed rail network.

The latter probably will never happen in the US.

Considering the US has far fewer people far more spread out, with two major sets of mountain ranges just in the continental US probably not. It might be possible to have high speed rail on either coast with a single rail line following along a route near I-10 east=west. Even then it's a lot of nature to overcome.
