(throwaway account to protect friends at Waymo) data points of 2: 1. took a ride, at one point a sudden violent sewering and breaking for no apparent reason - explanation from the backup driver - the truck in the next lane was too close. Then it couldn't take a left turn into the parking lot in front of Waymo HQ and was just stuck even though the maneuver was simplest to anyone. remote driver couldn't do it anything and backup driver had to do the 'normal driving'. 2: spoke to someone (again a waymo employee and her friend) just after the ride and the friend was visibly shaken and verbatim expression "worst ride of my life". This is all around the MV campus and in the last couple of months. So Waymo's claim seems way off unless they are talking about absolutely fixed paths, much like a public transit and maybe, just even then, a big maybe.
