the real issue is getting land to run the trains on

rail is point to point, but you can drive on any road in a car (if it isn't badly grid-locked)

rail would clearly benefit N-S routes on E, W coasts & up the front range, maybe TX triangle but the initial cost is high

with cars you just keep paying incrementally

the ... uh... 3rd rail is that autonomous cars can really put a crimp in rail
