How many of those rides required human intervention by Waymo's remote operators? From what I can tell they're not sharing that information.

I worked at Zoox, which has similar teleoperations to Waymo: remote operators can't joystick the vehicles.

So if we're saying how many times would it have crashed without a human: 0.

They generally intervene when the vehicles get stuck and that happens pretty rarely, typically because humans are doing something odd like blocking the way.
