This is an excellent article. Didn’t have an opinion before but now I think HSR is bullshit. Because physics. By similar analysis, I think hyperloops are bs as well though perhaps slightly less so because the load wear aspect is missing.

The other pro-airplane take is simply that HSR requires consensus-layer changes to L1 whereas airplanes are mostly L2 with relatively lighter L1 work required (pushing to change FAA and a few other regs), and doing things at L2 is 10x easier.

My heterodox take on US transit is that if infrastructure problems are too hard to solve, the transit of the future is airplanes, and we should just make airplanes better by (i) making them zero-carbon, and (ii) improving comfort by greatly cutting down airport security
