Look at the route California's HSR takes [1]. That's a map drawn for short-term political gains, not long-term utility.

Unless we develop technology that cancels out inertia, that track is speed limited for much of its route. Comparing non-American infrastructure costs and benefits to American infrastructure is misguided because American infrastructure costs unreasonably more [2].
