It’s misplaced ire.
It doesn't matter if Tesla succeeds or fails. All car companies now have to meet fleet emissions targets and the way they're going to do it is by building electric cars, either battery electric or fuel cell or both.
Somewhere around 2013, he claimed Tesla would launch a "fully autonomous, L5" in 2 years, but it would take another 3 years of regulatory approval. Clearly a gross misrepresentation of facts.
I take his claims with a massive pinch of salt, while also appreciating that trait is somewhat necessary to solve the problems he's trying to solve.
Either a) he is lying, or b) the CEO of multiple companies worth a combined ~$100b is delusional to the point of being unable to recognize basic facts. Pick your poison.
