Of course UCC applies, but again, where is a legally binding, contractual obligation assumed from marketing speak that is not binding? If you can show me specifics of anyone's contract with Tesla where it states that FSD will be fully functional on x date, I'd love to see your evidence.
I can't do that. But I can show where you built a strawman argument with specific dates that nobody was actually making.
My evidence is right at the top above my comments in this post.
You asked for, and I quote you once again-
You said:Please provide a shred of evidence that says anything about SAE L4 in your purchase contract.
I provided it.
The description given by Tesla as part of the explicit purchase of FSD promised I was buying a system that would eventually deliver capabilities at least equal to (if not better than) L4 SAE.
Rather than admit this was true and proven, you then kept trying to invent arguments nobody made while continually pushing the goalposts further away.
