This is just one case, we need to know the relative incidence rate before we can state anything. Even if we could somehow prove that a human driver wouldn't have hit the women that still doesn't mean that self driving cars are not massively better than humans: if self driving cars prevented hundreds of deaths they would still be better even though they miss this one situation.

Of course in the end self driving cars need to fix the bug that caused this to happen.
