There's no formal definition for "full self driving". But perhaps we could tease out a definition we can both accept. Let me start. My elderly Dad is a legal licensed driver who drives every day. FSD drives much better than my Dad in every way you can possibly measure. Can my Dad fully self drive or not?

Your Dad cannot fully self drive (I am a huge fan of Tesla FSD given that no other equivalent option exists in the market at that price point, but I have had to take over and drive it, at least as of the most recent free demo last Christmas season).
A more objective definition is any entity that is not willing to take on the financial liabilities of driving is not capable of full self driving. The minute Tesla says they agree to take on full liability is the minute I buy and use FSD for all of my trips.
