What is he doing? Going back?

Fuck him; he's irrelevant anyway.
His beloved Tesla wouldn't be shit without sucking on the teat of government subsidies
It's just a matter of time. Big guys (Merc, BMW, Audi, Porsche, VW, Lexus) are switching to e-vehicles already now. In like 10 years nobody will even remember what Tesla was... lack of new models/designs, poor build quality, expensive post warranty service/support - things don't look good for Tesla.
