Multiple people have already died in San Francisco due to these trash heaps. I can think of at least 2 confirmed incidents where the robo-taxis and their inability to deal with unusual situations has gotten people killed. One was very direct in which the car ran over a pedestrian, and another was somewhat indirect but still clearly responsible. San Francisco has notoriously narrow streets and 1 or 2 (I can't remember specifically at the moment) robo-taxis blocked a roadway and prevented an ambulance from getting to a patient that died before they arrived because of the delay.

In both instances, they didn't have passengers, so I think that made them a lower priority for the human interventions.

And California is still dragging its heels on cracking down on this bullshit. Someone rich will have to die first. Poor people don't count.
