> When you build a car you do it from very precisely controlled sets of inventory... You should do it from... Remember, Tesla's shtick for a while was to claim that the legacy automakers were dumb dinosaurs who didn't know code, and therefore Tesla would show them by building sonic velocity lights out dreadnaught factories where there weren't any tolerances at all, and... currently builds cars on a line that's basically indistinguishable from what everyone else uses. In throwing out everything the "dinosaurs" did, it's entirely possible they threw out a range of useful things as well like "The number of parts delivered equals the number of vehicles to be built."

Fair enough, they might be building them from large chunks of stock. Still, that would be a monumentally stupid move, you could easily forget something even more crucial like that, for instance a circlip on the steering housing. That would be a real surprise, better hope you have paid for self driving if that ever happens ;)

  > they might be building them from large chunks of stock. That's not how it works, though. Pretty much every single item in a car, except maybe for some screws (which would be identified by a batch number, though), has a unique S/N, and they know which car is built with which part, so that they know which owners to ask to a service center if there's a recall. It's not like they just tak a part from a pile and don't precisely track what they have left. Source: used to develop a MES for an automotive plant that manufactured brakes, airbags and seatbelts.

    If you will take some time to read up on Tesla you'll see that they have their own unique processes. What I describe is apparently how Tesla works, I'm aware that in normal car manufacturing plants that is not how it works.

      I would assume that bunch of these processes are mandated by the regulatory bodies – at least in EU. So while they may have some unique processes, it is unlikely that they can avoid the requirement for traceability.
