If Grandma June accidentally hits the accelerator, jumps the curb and kills a kindergartener, we can throw her in prison. She is held accountable for her actions.

If Grandma June is sitting in her "self-driving" car and it spontaneously accelerates, jumps the curb and kills a kindergartener, what can we do? Who is held accountable?
Something something "fix the problem, not the blame", but accountability is part of fixing a problem. Improving numbers in the aggregate is good, but it is not (and should not be) the sole matter in discussion.
