It looks like a cool technology. But I wonder what went wrong with our society when you need stock quotes while driving, and the kids needs movies to sit down and behave. He kind of went around the subject of getting emails to your car. And that is good. You shouldn't be deleting viagra spam while driving.
Another thing is privacy and security issues. Pairing GPS with online access I see a real potential for misuse. And I hope it will never be so tied into the "car bus" that you could plant a trojan in there to disable the breaks.
