Waymo navigates autonomously 100% of the time. The human backup's role is limited to selecting the best option if the car has stopped due to an obstacle it's not sure how to navigate.
Interventions are a term of art, i.e. it has a specific technical meaning in self-driving. A human taking timely action to prevent a bad outcome the system was creating, not taking action to get unstuck.

I think there's an interesting lens to look at it in: remote interventions are massively disruptive, the car goes into a specific mode and support calls in to check in with the passenger.
It's baked into UX judgement, it's not really something a specific number would shed more light on.
If there was a significant problem with this, it would be well-known given the scale they operate at now.

This is why its limited markets and areas of service: connectivity for this sort of thing matters. Your robotaxi crashing cause the human backup lost 5g connectivity is gonna be a real real bad look. NO one is talking about their intervention stats. IF they were good I would assume that someone would publish them for marketing reasons.
