Add to that, car to human-driven-car, and car to human (police officer, traffic coordinator) communication. Sometimes the communication needs to be complex (I.e. Verbal). I've had a few instances when I've had to negotiate to unblock a traffic deadlock, mostly when a two way lane is constricted to one vehicle only due to parked cars, or a HGV which is too big to drive past. In London this happens quite frequently. I really cannot think how an autonomous car, with no human inside, could handle these scenarios.
