> I have seen very little evidence of accidents caused by that kind of distraction.
One of the very few actual collisions in SF involving a Waymo was a rear-end accident where the guy behind the Waymo was staring at a phone at a stop, then when the cars in the next lane started moving, he started moving without knowing what was happening. Which is quite common. Looking down at your phone or at the car's console while stopped at an intersection is a bad idea. If you are forced to do it, it's important to keep in mind the need to look around for a moment before you begin moving again.
