CarPlay (and Android Auto) are designed to only interact with the InCar Entertainment hardware as a display, HID input and limited ancillary hardware. It pushes Video to the display and pulls GPS data, Voice, touch and button inputs. Apple actually dictate that the ICE system cannot store any data except connectivity (Bluetooth connection keys), everything else stays on device.

I am not going to go as far as say that OEM and aftermarket ICE aren’t able to extract information through CarPlay, and I will acknowledge that they will try to get user data through their own interfaces for the benefit of their own interfaces. I would never trust an OEM that forces users to not use CarPlay or Android Auto (ehem, GM).

I am confident that the only reason GM are introducing their ICE platform (codenamed “Edsel”) and blocking CarPlay and Android Auto is because they believe they will be able to profit from selling user information to data brokers. I am also confident that Edsel will be just as disastrous for GM as its namesake was for Ford.
