I don't work at Tesla, so I don't know where they have their clusters, but there are obviously many cloud providers who would be more than happy to sell you as many petabytes of storage as you would like to buy.

> I’d like to remind you as well that Google, aka Waymo, had their nn accelerators for half a decade already.

That's true, but you need something mobile and low power for a car. I don't know if Waymo really has an equivalent there.

Also, it's an advantage for Tesla to have their own regardless, because of cost. Tesla can probably make their FSD computer for $200. If you are a third party and you want to buy Waymo's solution, they will sell it to you for thousands.
