Musk is insanely optimistic. Thus he makes those kinds of statements. But if he were not so optimistic Tesla probably would not have gotten where it is today. We take the bad with the good. Wise folks ignore Musk's timeline statements.
If we were talking about you or me or others on here I'd have no complaints. While Musk is the CEO, effectively he is Chief Technology Officer of a public company. They cannot be talking out of their asses as what they say moves markets. He's already gotten in trouble with the SEC and lost his Chairman status over it.
Where I differ with you is your dismissal, "everybody knows he's full of *sugar*". <- no, not what you said but what you really meant. He's a C-level exec and as such he cannot be blowing bullshit out into the public. Notice you don't routinely hear from May Barra, right? When is says, and this is as much of a direct quote as I can give san suffering through the entire Ark interview. BTW, remember what Ark is. "I'm 100% certain, by the end of this year we'll be feature complete on FSD.... Welllll......", <thinks about what he just said>, "Yes, positively, end of the year".
I've spent decades working with people in Musk's position and they cannot say that unless they know that. I say that because they wouldn't be at that level if they were that incompetent. Consequently, it's either a true statement that should have been in an SEC filing, or it was complete BS and he deliberately said complete BS in which case the SEC needs to get involved again, or...he actually is incompetent in which case the board needs to get involved.
Consequently I, for one, believe him. The alternative calls into serious question the survivability of Tesla. Frankly, there is very little that needs to be added to NoA to make it good on secondary roads. 1) recognize traffic lights, stop signs, yield signs (or just always yield), speed limit signs, construction signs, and checking and turning at an intersection. Then there is managing a parking lot. One thing that happened there is serveral people violated their NDAs and released film of it working. It may well be we aren't hearing anything about it now because they learned from their mistake about what level of confidentiality a non-employee can be responsible for keeping. They could sue a non employee for violating an NDA but for what. People tend to value their employment and, with very rare exception, fulfill the terms of their NDAs.
Of course survivability is as it relates to how high of an item FSD is to them. For those that are infinitely more concerned with 0-6 in under 3 secs, well, FSD is a non-issue. Ditto for those who are passionate about electric. For me, the driving force was FSD.
