Train tracks are the train tracks of the future.

Trains are far more efficient than cars, especially at scale.

Assumes everyone is in medium to high density urban areas.

I like the idea, rural life excepted, but hard to imagine sprawl will ever be replaced.

It doesn’t. Trains cover the same distances as airplanes. Take a train across Washington, or anywhere, most of the stops are small towns.

Light rail, busses, and robotaxis cover sprawl.
