Find the word "autnomous" in any Elon tweet. Feel free to post it here. Elon has talked about "FSD" but to my knowledge, has never used autonomous full self driving. There is a difference. The cars, with current hardware, can steer, accelerate, and brake on their own, so "L2 Everywhere" would meet that - just requiring a driver ready to take over when the system can't handle an edge case. And, of course, all liability being the driver's.
That said, I purchased FSD for our '17 M3 prior to the change in language about FSD. If Tesla finally concludes the current hardware cannot do autonomous full self driving, purchasers might expect some compensation. (Our MY had FSD added in June 2020, so L2 Everywhere is what I reasonably expect for that vehicle.)
