>My understanding of GM is that they outsource almost everything.

Every single automaker outsources nearly everything under the bodywork related to engineering and development to their suppliers. VW, Renault, BMW, Mercedes, etc. all of them do it.

True, but outsourcing hardware components and outsourcing software aren't the same. Even when the hardware is actually very software-heavy, and designed to super specific requirements from the buyer, in the eyes of the supplier it's still a product. But outsourced software invariably becomes a project, with all the incentive misalignment that's implied by the term "billable hours". Even when that's technically not how the contract is set up.
