A Detroit Auto firm took a mod 3 completely apart.
And breaks it down, the good the bad and the ugly.

What else would you expect from people who don't know how to design and build mass produced cars?

There conclusion was the mod 3 would be a quantum leap in technology had an established car manufacturer made the car body.
The worst thing by far about the whole machine is the body.
The battery is no less than amazing, BMS is more advanced than anything else they have seen and the motor may be from the future.
But the body is holding everything back.

They're pumping out material for the retro-modders. Make mine a hardtop station wagon:

I wonder about the serviceability of this miraculous battery pack. All the electronics integrated into the battery pack. Having everything together is great for efficiency, cost and manufacturing. It isn't so great for service.

What happens if one of those components breaks? Munro compared it to cellphone technology. Cellphone and most electronics today are not designed to be serviced. They are designed to be discarded and replaced if anything breaks.

Or like Chrysler's Totally Integrated Power Module (TIPM). That's one thing I hated about my Ram--all the lighting functions, displays, switches, etc. run through the damn TIPM, so if one of those functions fails, guess what has to be replaced? And guess what's a lot more expensive than, say, a simple flasher relay?

They show some up close footage of the battery pack in that vid and it appeared that some one tore into the battery to harvest some cells for reverse engineering. The battery pack does not appear to be "take a part able" with out a hammer and chisel.
Unlike a leaf battery where once I get the clam shell of the battery pack open I can easily take it apart the cell stack it's self with my electrician tools. Which are just insulated versions of common hand tools.

If one cell fails prematurely taking apart the pack to harvest the remaining cells makes sense, but if the pack is nearing end-of-life all cells are on their way out and the exercise becomes futile.
If Tesla packs have a low premature failure rate there's no reason to make them easy to take apart, but it would make them structurally weaker, heavier and/or more expensive.
So Tesla does not plan for the cells to fail. They plan for them to succeed.

They planed to make it easier to toss the battery in the dump and forget about it.
That's part of teslas MO. Engineer as stuff impossible to make it impossible to work on.
