Having ridden in a lot of BYDs when traveling overseas I think you paint too bleak a picture. They're everywhere and reliable enough to seemingly be the preferred cars for uber drivers. Some markets might tax them out of existence but I expect others will gladly take perfectly serviceable cars on the cheap.

Tesla is still kicking and they had all the same problems at one time or another. I mean until this year we also massively subsidized every EV sale so pot calling the kettle black.
