I took a Waymo robotaxi in San Francisco a couple weeks ago. It was easy to use and I felt very safe; generally they drive like your granny. My second ride we ended up briefly stopped behind someone trying to do a left turn in an unexpected spot, and the car wavered left and right for a moment as it tried to decide what to do, not unlike human drivers. Given Tesla’s not so great record on full self driving, I think given the choice I would probably stick with Waymo.
