>>Why would they call it "mostly" if the idea has always been that it'd be "full" when it's done and out of beta?

Because "Mostly..." is the truth, and then when it is actually "Full..." they can come out and announce that fact with great fanfare. and they would have been honest.

Hell, if they simply called it "Supervised Self Driving", it would be honest, and actually match even your glowing description.

But they do not. Your and Tesla's idea that using the added tagline "(Supervised)" as a legal weasel-word does not work either. "Full Self-Driving (Supervised)" is literally an oxymoron. A thing either drives itself fully, or it requires supervision. One contradicts the other.

IIRC, the "(Supervised)" bit was added well after the first fanfare with only "Full Self Driving" alone, when problems started to appear. And the common initials are "FSD".

Even if the reality of the feature set meets your glowing description, the problem is the small percentage of cases where it fails. I'm sure the guy in Florida who was decapitated when his Tesla failed to notice a semi-trailer turning across in front of him was similarly confident, and the same for the guy in California who was impaled on a construction traffic barrier. The problem is that it is NOT FULL, it is only full self driving until it fails.

>>And as robotaxi shows, it's literally almost there.

NO, it shows the exact opposite.

Nearly two months after the much-heralded rollout of (fully) self-driving taxis, Tesla still cannot put a single car on the road for a single meter without a supervising safety driver. Moreover, there have been numerous reported instances of the cars making dangerous errors such as left turns into traffic, etc.

>>basically every single result is "Full Self-Driving (Supervised)", with very few exceptions.

Again, that wording is a literally meaningless oxymoron, containing two mutually contradictory statements ("Full" vs "Supervised"), thus open to whatever interpretation the listener latches onto. Moreover, the emphasis is on the first word — "Full" — which is the lie.
