I'm somewhat surprised (or perhaps I shouldn't be) at the generally negative tone of the replies here so far. Maybe this specific project isn't the winner or the exact right idea, but I am _extremely_ bullish on the basic idea of getting car nav / "infotainment" systems all running a common OS (be it Android or iOS).
I think it is an absurd inefficiency and possibly one of the most anti-DRY things out there that nearly every manufacturer has its own totally-different way of doing things on the HUD. Every radio operates differently, nav systems have varying degrees of quality, and overall the UX is about 50 shades of crap :) Reminds me of the days when every phone manufacturer had a different os -- and we see how well that worked out for everyone.
I think the future of automotive UI rests on the adoption of a standard os. Though I'm partial to iOS on my own phone, I'm happy to see either iOS or Android in our cars (or both).
Imagine this: You get in your car -- the UI is familiar and comfortable (though adapted for automotive use). You have access to your music library (sync'd from iCloud) instantly, you get your choice of GPS apps (Waze, Google Maps, Apple Maps -- lol, sorry just kidding), you can use radio services like Pandora or Spotify, etc. And yes, the manufacturer will have to make a custom app for the "manual stuff" like air conditioning controls, etc., but that's still a lot better than essentially having to reinvent the whole os.
Anyway, you get the idea. I'm very excited about this stuff and am fairly confident it's the way things are going. Whether or not this specific project is a winner is somewhat irrelevant - its a step in the right direction.
