I think this is too optimistic. Self-driving cars only work because they are in the minority. Can you imagine a city full of current state-of-the-art self driving cars and it not turning into a traffic chaos?
In particular, I think that self-driving cars cannot work fully autonomously without communicating with other cars or the road infrastructure. And I am not aware of any effort to create a cross-vendor car-to-car communication protocol.
There are trivial cases where pure autonomous following of traffic rules will lead to deadlock (or other issues). Take these two simple examples: 1) 4 cars arrive at the same time in a four-way intersection without signals or yields 2) on a three lane road, two cars from the outer lanes try to switch to the middle lane at the same time.
These are by no means difficult problems (I'm sure there are more difficult cases too), but they must be solved and so far they're not being worked on.

It's very unlikely that the situation could repeat again on a retry unless you think perfect symmetry can be achieved in physical world:)

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.
