i'm sure that every time this happens, it individually makes sense to do it at the time.
This is a microcosm of how large systems get developed in small pieces, by different people, over a long(-ish) period of time. It's the same in the software world too i think, but presumably has a lot more consolidation than cars (as software for cars might be less common, and thus employees moving between companies is unlikely to make any sort of cross-pollination like there would be for FAANG-like companies).
