Maybe after all cars become autonomous. Earlier there will be a hybrid period where both manned and unmanned cars drive together I think.
Even all cars become autonomous, the problem will still be hard I believe. Hard coded rules may solve the problem but relying on communication and cooperation will not be easy.
And computer-driven pedestrians, too - the car had to stop multiple times for turning left/right across a pedestrian crossing which was green at the time. (If you have watched the video, you have seen that most potentially dangerous situations did not originate from cars.)
