@PJ_Evans @mrpresidenttom @thomasfuchs That's the point: Musk envisioned the Hyperloop as part of a long game to create fear & snuff out investment in CA high speed rail projects so he could advance the use of EV cars instead.
He's admitted this. His megalomania believes he's saving the world. He abstracted the Hyperloop tech for the Boring Company to advance the idea of underground highways, again, to advance EV cars. Not for environmental reasons, but for energy storage on *Mars*. Look it up.
