Surprised no one's mentioned it so far, but CarPlay / Android Auto aren't just features, they're consistency. Across makes, models, years. I know what I'm getting when I connect my phone - and if anyone uses my car with their own device, they get their own dashboard, as well. One interesting use case I saw was a couple where one used a left-to-right interface and the other a right-to-left UI. CarPlay makes this easy, because the interface is linked to your own personal device.
