I suspect (but know nothing about manufacturing) that 90% of quality is boring, tedious things like quality control checklists, documenting processes, training low-level staff and so on.
Neither of these things strikes me as something Elon Musk would consider time well spent. He's more like, "cybertruck!", "really self-driving this time!", and more recently, running Twitter.
...and yet somehow he manages to launch and land way more rockets to space vs what NASA has been able to do for the last 50+ years...and at a tiny fraction of the cost.
Well, first, that has nothing in particular to do with mass-producing cars. However, also:
> Rockets from the Falcon 9 family have been launched 204 times over 13 years
(Also Falcon 1 launched five times).
There are multiple _single types_ of US and Soviet rocket which have launched more times than that. Atlas I, for instance, 514 launches. Titan II, 396. Kosmos: 610. Soyuz: _1,964_.
