When Apple did all this in phones it was unique. There was no Tesla of phones. But there is a Tesla of cars and it's tough to imagine what unique thing Apple could bring to the market.
Apple typically productizes mature technology and ensures that its products are designed well. Tesla is an early adopter and productizes immature technology which it overhypes and overpromises on (e.g. self-driving).
Apple's manufacturing quality control and attention to detail is also generally pretty impressive. Tesla products looks impressive on the outside but feel cheap on the inside, and there are a lot of issues with the quality of manufacturing. Apple uses nice materials and Tesla uses cheap materials.
Apple making a car always struck me as weird, though.
I would argue BMW or Mercedes are much closer to being the Apple of cars - they aren't early adopters of new technology, and their products are immaculately designed (though using a much different design language than Apple does) and are and feel expensive, unlike Tesla's cars, which look nice but feel like toys.
Today, not so much.
