> Then build railway systems

Unfortunately those aren't made at McDonald's or at any other fast service establishment. In other words they are neither fast nor cheap to build.

If we exclude local commute, the US has a pretty good transportation system, as it is, road transport is indispensable in this mix, at least for now. It would make more sense to convert cars to EV's and use the saved fuel for trucks than to redo the transportation system.

The highways are already there.

Flippant transit-signaling to say "just build railways." The people eating shit for diesel prices have little power to do so lol.
