I didn't really get any solid response to my post yesterday in the main investor thread which posed two questions, so I figured I'd try here instead in the resource thread (is there a cell thread ?). You folks are likely counting the tonnage from the mine deals and translating it into GWh of cells, and so you ought to be more cognisant of this issue than the general TSLA investor.
Running into fire and police vehicles that have their flashers engaged is not all that uncommon. Been so for years. 100% sure it's not AP or FSD. People get fixated on the flashing lights and if they are not fully aware often run into them. Tesla issued a patch to AP the last time this came up...

The two questions were,
- Q1. Can the cell suppliers (and their mineral suppliers) continue to meet the total annual increases that the historical evidence suggests will continue to be met ?
- Q2. Can Tesla continue to capture at least a 20% market share of that cell supply for vehicle use ?
I had expected critique of my S-curve matching technique on various grounds, so have run the analysis myself different ways so as to see if that casts any light on Q1. It turns out it makes very little difference, and it didn't seem sensible to include that level of detail in the main thread, but I'll throw it on the table here so you can see that the analysis is robust, given the underlying assumption that the cell supply chain will meet the annual demand increments. (hence my Q1, to check if this is realistically the case).
The analysis I presented yesterday showed a history match on the % of the total annual motor industry production that is met by EVs. A valid critique of that would be that the motor vehicle production numbers in recent years have dipped, therefore this flatters the EV% uptake, and so will naturally lead to a prediction of a more rapid uptake rate than is realistic. Therefore I have also run the same analysis using the actual EV numbers (EV#) as the historical 'seed' which strips out this effect. The next level of criticism is to say that perhaps the EV uptake has been fundamentally constrained by battery growth, which in turn displays itself also via the cells/vehicle parameter, and so I have again run the analysis using cell production (in GWh) as the seed. It turns out that all three approaches give very similar curve trajectories with barely 6-months between the respective midpoint penetrations.

Therefore the analysis so far seems pretty robust in respect of the historical adoption data that is used as the seed in the optimisation of the three paramaters that are matched in the process of generating the respective S curves.
But is it realistic to expect the cell industry to meet the requisite annual capacity adds ? Here are those three curves again, but this time in cell terms for just vehicle usage:

As we all know the cell supply needs to 20x from where we are now, for vehicles alone. My hypothess is that it will achieve this as vehicles are - in general - able to pay a mobility premium for cells. Therefore vehicles will tend to outbid stationary storage if cell supply becomes a limiting factor, and since stationary storage is also growing strongly the evidence suggests cell supply has not been an industry-wide constraint so far.
But it might become a constraint in the crunch years to come, so here is the graph of (vehicle-specific) annual capacity additions this implies:

As you can see in all three forecasts the peak is at about an annual addition of 1,000 - 1,100 GWh and that peak lasts for three years, with a further two years either side above 800 GWh adds per year. That is a pretty good (i.e. stable and long-lasting) peak for a supply chain to scale itself to meet.
In annual % growth terms the worst is sort-of happening now, which one might regard as a training regime for the subsequent phase.

So, I say again to you folks who are looking at the resource question, can you (Q1) see any show-stoppers in the growth of vehicle cell-supply at an industry level ? and (Q2) to what extent is Tesla positioned to regain ground (that it has been losing) in respect of vehicle cells ?

I'm minded to next look more deeply into the possible growth trajectory for stationary storage, but it makes a lot of sense to flush out any cell growth constraints now before it gets any more complex.
