Maybe it's a bad business decision on Apple's part, but no one should be surprised that "iOS in the car" is for iOS devices. Google's business model is totally different. As long as you're using Google services they could care less what hardware or OS you're using.
It's just typical stone age Apple business model, but it's certainly worked for them looking at their bank balance, yet it is too old and walled garden for cars. Whereas goolge and the others are a lot more open. But as said CarPlay will most certainly not be the only option for these cars.

Ford will be dropping SYNC from their cars starting next year. That's the on-going rumor we heard so far. It's most likely accurate.
But this is about CarPlay anyway.
They will still be supporting it though which is all that matters. And yes, I have read rumours they have been looking into Blackberry's QNX, actually I also read they are looking to change current car systems to QNX too, so either way I should be covered
