We are on the same page I think, the skepticism is shared: I'm in medical and not automotive, but much of our PLM process is shaped by what was learned in the automotive and aerospace worlds. It boggles my mind to imagine how Tesla can get all of the responsible parties to even sign off on the documentation alone at the speed they work. I am quite serious (and I think correct) that if Tesla's process is as efficient as it appears, they are sitting on a gold mine for consulting considering all the organizations in regulated industries that are incapable as moving as fast. Musk wants to change the world? Sharing this secret would count.

Another question that popped in my head: what did the requirements look like that allowed such a huge (I assume) CPU and memory budget available that they could improve the system with "six times as many radar objects with the same hardware with a lot more information per object."
