That doesn't solve my issue at all, though it might be fine for some. I use my iPhone for everything - maps, podcasts, music, and of course phone and messaging. When I get in my car, I want it to instantly become my mobile office connected to my iPhone. Building those features into the car, regardless of the technology, does nothing for me if it duplicates rather than synchronizes with my out-of-car life.
