Agree. And I'd like to see an approach similar to an NTSB investigation of an air crash. Not to place blame, but to identify root causes and mitigate the chance that they recur.

Air travel is exceptionally safe. Has been for many decades. Yet we still investigate any air crash because any crash means something went wrong, perhaps something that can be corrected.

Self driving cars need to be treated the same way, at least for now, and until well after they have demonstrated themselves to be safer than human drivers.
