In practice, humans don't make these decisions and autonomous cars won't either. They'll default to brake and stay on the road, lacking other options, because it's the simplest option and doing aggressive dynamic things to try and prevent a bad outcome to outsiders is not really likely to have a better outcome.

I agree that at first autonomous cars won't do better. It is much easier to program within parameters like "stay in your lane". But in 100 years time I think they will have more options.
