If you can't get people to stop buying $70,000 gas cars I don't know how you're going to get them to stop buying cars that don't include whatever car-to-car communication system you can come up with. People don't do what's good for the commons; instead they do what they think is good for themselves. So for a long time going forward, autonomous cars will still have to deal with other cars that are basically rolling bricks. Since they can't count on any smarts or any of the communication that you speak of, they have to rely on themselves. So eventually, yes. But meanwhile we do need the fallback of autonomous discernment.
