I just hope it does not end up like video games, where they can sell an unfinished product and patch it later.

Too late. This is already the case, I don’t know of a single EV that wasn’t buggy on release and still buggy a year or two afterwards as the manufacturer hunts bugs in a leisurely pace. It already is like in the gaming industry. Don’t buy an EV that isn’t at least one year old on the market or you will become their free of charge beta tester…
