>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.
You just said my Dad cannot fully self drive, but then proposed an "objective" definition which my Dad unquestionably satisfies.
Are you conceding that FSD is in fact correctly named in terms of its technical capabilities, and only falls short in terms of legal liability?
I should note that my Dad is a perfectly competent driver who has not been in any car accident in the last 30 years (at least, I'm not aware of any). But he drives in a way that makes me feel somewhat uncomfortable as a passenger. It's hard to explain.
