Lapse in focus is such a great point. If we looked at the number of accidents caused by very human errors such as "lapse in focus" and "sudden medical events" etc. which we would 100% expect to go away when offloading tasks to any computer, the statistics of accidents remaining becomes the bare minimum for what computer-based automated driving must achieve.

This is compounded by the system mistakes likely being hard-errors. A computer hard-error vs. human lapse of judgement is potentially the difference between the vehicle slowly crushing a small child as they scream and beg for help vs. a human stopping as soon as they felt/heard something. Context matters.

The compared error-rates must consider if it could have been avoided or mitigated, the near misses, the human vs. computer type of error, and how hard-errors may lead to horrifying scenarios.
