So let me see if I understand the economics here. I'm an automaker and I want a fancy UI on my dash (like Tesla or EQS). So I put in the big screen and then add the Apple extensions to allow CarPlay 2. But what do I ship with the car? A cheap and quick UI with basic features, or do I have to write a second fancy UI that looks good in the showroom, on test drives, and when the battery dies in the phone? How much time and money do I spend on that? If I'm Toyota and shipping cheap Corollas, what kind of screen do I pay for on that car? Triple-wide LCDs aren't exactly a commodity part. So is CarPlay 2 something only for expensive cars?
