I see the Waymo cars while I walk to lunch (AZ) quite often. One time while walking through the crosswalk a Waymo turning right cut me off as I started into the crosswalk despite my having the walk indicator. This seems to be a very difficult scenario for a self-driving car as there are often people at the corner that are either crossing the other direction or just waiting on the corner. I sent them a note via their feedback link, but never heard back.
