> Health - beyond the obvious effects on the emergency room, what else? Ambulances willl quite clearly be affected. Why would someone wait minutes for one to arrive when they can just hop in an autocar to go the hospital? Or would the entire emergency room itself be on wheels? (Less likely.)

Well, the car can't go through red lights or overtake in certain locations to get to the hospital more quickly. That could be an easily ignored issue in some cases (if traffic is light or if it's easy to get to the hospital from your current location), but good luck if there's a traffic jam or the car needs to ignore certain laws to save your life.
