Apple's Carplay may also be their first step in a 'automotive operating system' for partial or full self-driving cars. I could also see them building a 'development kit' car, with documentation to allow 'chassis-builders' and/or 'coach-builders' to create their own customized designs.

I hope to God I never have to ride in a vehicle where its core safety-critical functionality in any way shares code with CarPlay.

Yup. I deal with hysteresis on mine that will flip back and forth between day and night view every second if the ambient light is borderline.

And other things. Car Play is great, but currently one of Apple's buggiest products.
