I generally wouldn't trust big mining corporations to do the right thing but that's some extremely negative framing. For standard EV cars in Australia only 20% of new sales are EV,…

Weirdly, one of the arguments Musk advanced was that is was all a front for the CIA, which I'd guess is closer to hard power that he was dismantling. Not something you'd expect to …
