The issue is not a confusing road network, it's that Waymos require a modicum of grace in other drivers to operate. They aren't super aggressive, they'll defer to pedestrians and other drivers, they drive safely. That I think is where they'll find problems when expanding to locales with less than conscientious drivers.
