In relation to the 4680 ramp, I think it is on track.
Drew(?) said yields were good.
So what they are doing is accelerated cycle testing of the cells.
If there is any issue impact on cell longevity, they are making production changes and repeating...
IMO there is a good chance several versions of the cell are in the test cycle in labs, and some test cells are driving around in cars.
What they want to achieve is, the ability to give an 8 year warranty on the cells, that doesn't need 8 years of testing.
The also announced suppliers are doubling production next year, some of that may be 4680, but again those cells need to be tested.
It is possible that some of that increased production is in proven 18650, 2170 and prismatic LFP formats.
Like FSD, volume 4680 cell production may take a bit longer than we initially expected, the end result is way more important than the timeframe.
Same goes for the refreshed Model S/X, if it was easy, or a minor upgrade, Tesla would not find it hard to hit the target date. These delays tell me the product is worth the wait. I'm sure they could have cut corners and delivered a less ambitious upgrade earlier. In the long run, getting it right, wil pay dividends.
Overall earnings was a solid result, around what most people expected.
In relation to regulatory credits, Tesla has a good idea what the numbers will be, that gives them a bit more flexibility on pricing and margins.
While it does remain a talking point, I;ve never seen any evidence that these credits are going away anytime soon.
