Almost all hardware companies don't understand or care about software at all. They see "software" as just another line item on the BOM, like a screw or a gasket. You source it from the cheapest supplier and then attach it to the product somewhere on the assembly line. The idea that software is the interface to the user, a signal of quality, part of product differentiation, an ecosystem in which future products live... none of this even remotely occurs to most hardware companies, especially car manufacturers.
