They're saying the quiet part loud: They don't want CarPlay Ultra because they want to be able to gauge their customers with more monthly subscription services for things like Heated Seats, Maps, and every other basic feature that cars 10-15 years ago just had from the factory. I will never EVER pay for any in-car services. Ever. When I buy a car, I expect it to work and everything I paid £10000s for to be included. I will never buy a car that paywalls its features.
And not for nothing, the Auto manufacturers own infotainment systems have always been laughably ****. Just garbage software that's sluggish, ugly, and designed and programmed by people who have no idea about design or programming.
