I agree and disagree. Apple, at its heart, is a software company. The hardware is there to accomplish its software goals. I think GM is starting to understand that cars, at some point down the road, will be just the hardware that software runs on. GM, and other car MFG's, if they don't adapt, will be relegated to just making the equipment that other people's software runs on. Apple like to control the user experience....like they REALLY care about this. Does Apple need to make their own displays to control the iPhone experience? No, but for the first few iPhones they were basically the design shop for an outsourced screen MFG. Apple also finally just started making their own chips instead of partnering with chip MFG's because of the level of control they wanted. Granted all of these things are related to "computing" but the hardware of a car will become less important as the software of the car becomes more advanced.I’ve never understood the notion of an ”Apple Car”. It’s so removed from their general business that it just doesn’t make any sense to me. Much the same as the idea of Porsche coming out with their own phone or computer.
This could be correlated to Apple partnering with an existing automotive MFG to make a distinctly unique vehicle. However, I could also see Apple just continuing down the path of CarPlay and leaving the hardware to others. I think either path forward would not be surprising. The reason why your example doesn't work is because Apple cares about the vehicle because it is a mechanism by which their audience would interact with their product, the software. Porsche has no audience in a computer or a phone so there is no correlation.
