> They can't even build their own infotainment systems anymore. [...] I can't overstate how catastrophically stupid this is

Car manufacturers have for a very long time acted mostly as integrators and outsourced a vast amount of components, from braking systems to windows, lights, gearboxes alternators starters and other engine parts, electronic harnesses, suspension systems, seats, buttons and others. Lots of conglomerates nowadays even use common frames and engines ("platforms") across brands, developing engines is so expensive that they're sometimes shared across brands that aren't even part of the same groups. Infotainment and electronics are practically never built in-house, but instead purchased from Bosch, Samsung and the likes.

This makes sense, this isn't their specialty, the core market of vehicle buyers buy it for the car, not the infotainment system. Especially when talking about German cars, what they specialize into is the actual power train and quality of assembly. Not the radio.
