Take their power seats not stopping for obstructions: most auto manufacturers do not make their own power seat modules.
They buy those from suppliers like Bosch and Continental (yes, the tire guys): https://www.continental-automotive.com/en/components/seat-co...
But Tesla loves "innovations" that are just an excuse to vertically integrate in an inferior manner. That's stuff like the "superbottle" which integrates a bunch of parts you could normally replace independently with common parts into one (super easy to integrate on the assembly line) package
