Do you live in areas where traffic lights go out regularly?

Because for human driver it is a non-issue. It becomes an all-way stop and you take turns, it is easy. Traffic throughput slows down a bit, but nothing approaching chaos about it. If waymo can't deal with this, that's a problem.

Genuine question, do we have data for accident rates in traffic-lights-out intersections?

If I remember my research correctly, accident rates go up but fatalities and injuries go way down.
