> From that perspective, there will be a strong need for various rare earth elements. Leading to an insane amount of pollution. Are there any breakthroughs in rare earth extraction & treatment process?

What rare earth elements are you talking about, exactly? I keep hearing about the scarcity of such "rare" elements, but except lithium (which isn't that rare, it's just we haven't invested in the infrastructure), I'm not aware of the lack of any other materials needed for EV cells.




Yeah, there's a lot of nonspecific scaremongering; I think the bottleneck metal at the moment is cobalt, but Tesla and others are working on that. http://www.mining.com/tesla-delivers-bad-news-cobalt-price/
