I think it would be great if at some point some lanes of the freeways are dedicated for autonomous vehicles connected to a city or state-controlled system with some fallback. I suspect there is a fallacy somewhere in my idea, but I think the first step is to make some lanes only for autonomous vehicles on the freeway, and eventually all lanes as autonomous vehicles become more commonplace. I'm not a civil engineer, but I suspect this could eliminate a lot of traffic if all the cars are placed in the most optimal lane, assuming all vehicles on highways are autonomous.
