Just about everyone believes themselves to be an above average driver with a lower than average risk profile. And besides, it's not like we're just talking about replacing only the safest drivers' miles with AVs. We don't really know how safe Waymo is yet, because there's not enough data. It's pretty safe: it's more patient and cautious than most humans are willing to be and also has perfect vigilance; on the flip-side there's more situations it just doesn't understand. Waymo's goal is to be a more vigilant version of the safest human drivers. They're probably not quite there yet.
