> There exists a flavor of CarPlay — CarPlay Ultra — that does take over every screen of the car.
I wish software leaning Internet people stop framing that center console tablet as "the car". It's worse than people pointing at display monitors and calling it computers. They're just cheap complimentary tablets attached to the car. If we were to fully embrace the line of thinking that frame the touchscreen being the car, the Slate Truck cannot exist, since it lacks the car of the car. In reality it does exist, because that thing is just a tiny add-on unit of a car.
The reason why there's been zero cars with CarPlay Ultra is because those cheap tablets remote controlling features of the actual car that hosts it, like speedometer, is weird, and way too complicated, and plain unworkable, on top of being too controlling.
I'm not defending car brands, I find conversations with misunderstandings like this less than ideally productive. The 5.25" DVD drive unit is not the computer.
Huh? Your own quote literally does not frame the center screen as "the car":
