I'd accept a refund or buyback too, no problem. But I don't think that a court ordering specific performance is the only way that early FSD buyers might get free or discounted upgrades. That's not really what I was expecting.
If Tesla was ever ordered to refund every FSD package ever sold, how much money would that take? What sort of hit would the stock price take as investors priced out the "solving FSD will be worth a bajillion dollars" premium? I'm not sure Tesla could refund all its FSD sales.
