The fear for me was that Apple would grow quickly in the EV space due to its mainstream popularity, and then start doing the ecosystem thing so driving anything but an Apple car makes you a second-class citizen. Obviously it would only support Carplay and not Android Auto, and probably lack any sort of non-Carplay connectivity so you just can't connect your Android phone to it at all. Presumably it would also have a proprietary charger that doesn't work with other cars or vice versa.
