I don't think it's just a simple stunt. Apparently, the onboard computer on the latest Teslas is capable of mining BTC profitably at the current prices (allegedly).
It would be amusing to have cars mine when idle/plugged in, or better yet have any unsold inventory mining 24/7 (since electricity can be written off as operational expenses). I wouldn't put it past Elon.

I would be interested to learn more about that. I thought the bulk of the Autopilot compute power is in dense neural network inference which wouldn't be any good for SHA hashing.
