I really, really doubt FSD is the limiter of European sales. It's pricing and competition. The US car market is laughably uncompetitive, with most manufacturers opting to make luxury landboats. It's easy to compete when all your competitors refuse to introduce an EV under, like, 50 grand.
Absolutely. I know a couple of their early adopters in the EU and they were ashamed to drive their cars once that mess started. They've all since sold them (at massive losses).
