There's no external public visibility into it, so other than wilbeddow writing on HN, how would anyone else know about this issue? I have the opposite problem, where the Waymo takes the legal option on an unbusy street, making the route a lot longer, rather than making an illegal U-turn that a human driver would do, when there's zero traffic or pedestrians it could remotely possibly run into.

Which is also not captured in the statistics.
