I wonder what would cause this to all happen at a single location. If it's a "routing issue" like they said, it wouldn't make sense for all the cars to get stuck in a single spot like that.

I wonder if the radial symmetry and small radius of the cul-de-sac poses a challenge for GPS and lidar localization.

There was a waymo just parked for days I noticed recently in SF. 2 or 3 days it was just in the same parking spot (4 hr max) with it's lidar spinning.
