Hmm...one-quarter the cost of a highway? I'd love to believe it, but the tolerances in one of these are going to be a lot closer than a highway. Nevertheless, if they build it I might try it.

It'll be for high-demand routes, though, like New York to LA or Washington DC to Hell.

or Washington DC to Hell.

Shortest route on the whole system.
