...Is "disability dongle" the new "autonomous transit pods"?

For context, San Francisco being a city with billionaire tech oligarchs, lots of traffic, and OK but not great transit means there's a LOT of rich people who want to fix traffic by way of almost literally reinventing the wheel.

We already know how to move lots of people to a particular destination very quickly: some variation[0] of a bus or train on dedicated right-of-way. The problem is that America is specifically engineered to make operating transit unprofitable outside of high density urban areas, acquiring land for that right-of-way in high density is astronomically expensive, and increasing density limits to break this chicken-and-egg problem is a political nightmare in most places.

This is exactly the kind of problem Silicon Valley hates having to solve because it is, in a sense, the enemy. A good chunk of Big Tech got drunk on Ayn Rand, and transit in particular presents a problem that Objectivist philosophy is unwilling to engage with. To solve it requires both negotiating with the urban planning equivalent of a Soviet central planner and long-term subsidy through coercive taxation.

The pitch for all these projects is ultimately a complicated heavy engineering project to make a train seem less like a train and more like a tech product. Think like the Hyperloop, a concept for a vaccum-sealed tube in which "pods" could be shot through at high speeds. This doesn't need to exist, heavy rail can absolutely go 200mph, we can already bury it underground, and there is no need to have individualized vehicles aside from a mistaken belief that Americans are allergic to sharing space with other Americans.

The one version of this that actually got built is the Vegas Loop, which despite the name and the hype has nothing to do with Hyperloop and was just Teslas driving down a one-way tunnel. All the hype around it delayed actual transportation. As I hinted at above, federal politicians[1] in America would really rather you not take a train. Americans themselves will happily ride them[2], but getting local funding for it is a battle. And all the talk of hyperloops and pods made local politicians hold off on fighting that fight for a good decade, so there's a lot of transit we're missing, because the stupid sci-fantasy ideas never panned out.

[0] I am being very broad here - France has it's obsession with rubber-tired trains, Mexico City has an extensive BRT network that provides metro-like service frequencies.

[2] We abuse the shit out of commercial aviation to do things high-speed trains can do better, so it's not like we're afraid to share space. The only thing is that Americans don't know how to stay quiet on a train or plane - but that doesn't make the train unprofitable or impractical.
