>Google is working on a rival system, but one that doesn't require a phone - all the 'brains' are integrated into the car
And there's the answer. Google is working on it while Apple is delivering.
Microsoft delviers, too, but Ford customers seem somewhat unhappy with the Windows Experience in their cars.
I haven't heard of Intels Tizen for some time, are they still working on it?
QNX looks good to me, especially because car manufacturers have a lot of experience with it.
But providing connectivity to any android phone can be a problem, which android with which extensions and modifications on which hardware? Add Symbian and Windows Phone and we're in trouble.
Me? I don't even own a car anymore :)
