I know that anecdotal experience is definitionally just that, anecdotal. But I've had a handful of attentive London cabby experiences (and enough in-Waymo experiences) that give me conviction that Waymos are far safer than them. They're out there driving all day every day, it's obvious to me that a Waymo driver is going to be safer than even a professional.

One cabby pulled out of a t junction to end up alongside me on a motorbike – a Waymo would never do that.
