> There are also interesting innovations that become more possible as more and more vehicles become "smart" and connected - imagine a metro area that is influencing smart vehicles +/- a few kph to smooth traffic, or route vehicular traffic like networking traffic around outages/problems. And this "differentiation" will be easily retrofitted to every other vehicle since there is nothing inherent to vehicle construction that is required for that. Well, the idea itself is not bad, and I'd see this being as the one, and only way any form of "self" driving will appear — as some kind of centralised "air traffic control" for car traffic, instead of each car doing the very fragile SLAM based navigation, and complex sensor suite based driving, which is one dirt splat away from the crash all the time.
