I totally agree that those are all valid concerns.However, I am confident we will get those things figured out. Maybe the congestion won't be that bad because autonmous driving services might encourage ride sharing. I for one already sometimes use Lyft Ride for longer trips. Maybe we can increase incentives for that? Communities could create a fee for single passenger rides. In a way car pool lanes are similar to that and already might accomplish something like that. On the less punitive side I can see something like convoys decrease fuel consumption. My university in Paderborn, Germany was working on something like that for self driving trains over ten years ago. Of course it's much harder with cars, but we also have come a long way.
