Tunnels in cities and trains between cities are not at odds with each other. Let’s not be zealots about that. The tunnels seem fine to me within cities, but I am all for trains between cities.

I'm pro-transit (I vote for it whenever it is on the ballot, and take it frequently). I'm also skeptical of Musk at times, especially the promises about "full self driving" in Teslas.

That said, I find the urbanist/transitphile community's response to Musk's tunnel ambitions off-putting. Most of the criticisms I've seen seem to presume that a person who has revolutionized space travel and electric cars can't perform basic math about passenger throughput. Excuse me if I have more faith in Musk than the naysayers.

Please don't post unsubstantive flamebait to HN.

This is at least as bad as what you're scorning.

Perhaps he realizes that politically fail is impossible in the US? Not defending the guy, and I would much prefer HSR, but at this point acknowledging that automobiles rule and must be a part of the solution is worth trying.
