Saying this cautiously (as in, nobody really knows for sure how Tesla's organized internally) I get the impression that there's more than one group doing development over there. That's not unusual: when there's, say, 20 people working on the final release of 3.6, there's another bunch working on 3.7, a smaller crowd on 3.8, and one or two on 3.9. At the same time the systems engineers have dumped out the inspected 4.0 requirements and are busy messing around with features on 5.0. At least, that's the way I've seen it run on Big Development Projects, and those projects were likely
smaller than what Tesla's R&D efforts are like.
I wouldn't be overly surprised that Elon is only tweeting about, using the above example, the 3.x tree, seeing as that's the one with visible results, safe enough for the CEO to drive around in, and there's a high likelihood, given how close to release a 3.x package might be, that a delivery time may be forecastable. If he did mention the 4.0 or 4.5 releases, it'd be really fuzzy statements, if anything.
Thing is, though, is that every time Tesla puts out a major release, they learn stuff and the systems engineers get busy again. It's quite possible that a 3.x (especially 3.9.1.1
) is doing the manipulating-the-variables local minimum trick in a particular architecture. But a different, 4.0 or 5.0 architecture may have substantial improvements over 3.anything.
The above is definitely an optimistic, glass-half-full view of what Tesla is up to. As FSD-b testers, we only see what's come before and what we have right now; the future is somewhat obtuse. For all we know Tesla may have realized that there's no more there, there, and they're stuck. Get stuck badly enough and it's going to affect profitability and negate quite a few of Tesla's statements. Which would make the SEC really, really irritated. In such a case, a whistleblower could make quite a bit of hay, NDA or no NDA.
But there haven't been any whistleblowers like that, at all, from the inside. So, for now, I'd put my money on Tesla's people chugging along and coming out with better and better stuff. Maybe even hitting Level 3 despite those filings with the California DMV. (Remember: There's likely people rolling the dice
inside Tesla as well as outside. What's better: Saying one can get to Level 3, then failing, or saying that one is going to do Level 2, but then managing to pull Level 3 off? The first attracts regulatory attention; the second, not so much.)
We'll see when we get there.
