This is another version of "use public transport instead of throwing billions on futile self driving cars" -- it's the correct, rational thing to do, but it's not the American way!
Connecting every last rural area by train may have been a thing in the 1800s, but it's not really all that efficient to fire up a humungous train to carry one person. We aren't going back. "Correct and rational" doesn't exactly stand here either.
