An honest account of this situation would place at least some blame on there being a tall SUV blocking visibility.

These giant SUVs really are the worst when it comes to child safety

The best reaction from Waymo would have been to start to lobby against letting those monster-trucks park on streets near schools. They are killing so many children, I'm flabbergasted they are still allowed outside of worksites.

I bet we'll the the SUV mania in the future as something crazy, like smoking in a plane or using lead for gasoline. Irrational large size cars that people get because everyone it's afraid of another SUV hitting them in a sedan. The tragedy of the commons.
