Overall yeah, but that's why I focused on similar-scale regions. For long distances, like SF-NYC, I think the current US solution of planes is basically the practical one and am not expecting a coast-to-coast bullet train. What's slow and could be improved in the US is regional-scale travel, the 150-400 mile range. I was disagreeing with the person who started this thread who argued that that kind of intercity travel in the US is already solved by autos. It is sort of, but only if you don't mind slow and tedious travel...
