You'd need huge investment in high speed rail. Tokyo to Osaka is about the same distance as Chicago to Des Moines Iowa. 3hr train vs 5 hr car ride. We could do it... But the density of travel between those locations would make a project like that a very poor investment, so the government would have to pay the bill knowing it would be at a loss.

Then you build this rail.

That's the easy part.

Now I have to convince Des Moines to invest in better bus systems or trolleys to get people around in the city and the outlying residential areas. This is where these projects fall flat. Getting local municipalities to invest in public transit. Hundred people get off in Des Moines and unless someone is there waiting for them or they have their bike or left their car there. They're stranded.

Its not sexy. It won't get you re elected. It won't be done in your term.
