This report [1] seems to imply that around 35% of minor crashes aren't reported which is significant, but not enough by itself to move the needle too much. Another factor is highway vs surface miles. Highway miles would seem significantly safer on a per-mile basis (but I can't find any numbers to back that up), and with Waymo excluding highways for now they'd be all surface miles. I can't find data that breaks down crash rate by street type, but I suspect surface traffic has a much higher crash rate than highway miles.
