This makes no sense. Nearly every manufacturer adopted the past CarPlay despite Apple's "arrogance".
In the past CarPlay was only about infotainment, at a time when the car makers didn’t feel like they had a better system of their own.
Now the car makers care a lot more about harvesting user data, have passable systems of their own, and this time Apple wants control of all the screens.
Its Apple’s arrogance, but it’s also that arrogance meeting the immovable object of the entrenched car industry.
