This object identification and prediction capability can be easily overloaded. Last night, coming home from Summer Symphony (Idaho's big improvement on Frisco's Stern Grove), I encountered 30 or so drivers behaving rather erratically due to a small roadside meadow containing at least 75 deer, all of which could decide to cross the roadway en masse within a few seconds. I successfully navigated all this, but I would NOT want to be in a Waymo for this trip. And this was in very good weather; obviously bad weather complicates this scenario even further.
