There’s not much actual information about CarPlay yet, but it’ll be a long time before it’s in enough cars on the road to be relevant.
It also has the potential to fizzle out because Apple demands more control than their partners are comfortable with, like iAd, or their interests conflict too much with the partners’ interests without enough upside to the partners, like iTunes TV rentals.
CarPlay will become much more interesting if and when, say, the millionth CarPlay-equipped car is sold to a customer, which is probably at least two years away even if manufacturer adoption goes very well.
Naturally, as a developer of a podcast app, I’ll support it if I reasonably can. It’s probably easy.1 But I don’t expect CarPlay support to be a significant force in the market for a while, if ever.
I’ve heard that there will be a CarPlay simulator for iOS SDK. I hope that’s true, since it would help tremendously — at least, if I’m allowed to develop for it. Apple’s language about third-party apps suggests (but doesn’t confirm) that it won’t be open to all developers, being limited to partner deals like Apple TV channels and Siri features. ↩︎
