It's also worthwhile to point out that, although in this case the bad human driver was the immediate cause of the accident, at scale this will happen with some frequency, either from bad human drivers, bugs in the software or hardware, or just weird situations. The entire point of AVs is that these can also be corrected at scale: people who make excuses for the failure are removing the paramount incentive to make AVs as near to perfect as possible.
