Most automotive companies don't do software themselves and even don't have the skills to do it but buy it from a supplier or contractor according to their specification. At least that's the case for the infotainment domain I'm working with. So I guess those plans and concepts for self-driving technology also heavily utilize 3rd party software from suppliers who have specialized in that. In this case Apple would just replace the other supplier. Of course with the risk that the feature set and behavior of the software does not match what the OEM expects.
