What a laugh this story is, unless you've been the victim of one.
The California Public Utilities Commission extended the trial period of robotaxis period in San Francisco and the period of times each day they can operate. The slang name of the service, robotaxis, is self explanatory but if not, there isn't a driver. The cars are self guided. Locals are not amused and nor are a number of elected politicians.
There are issues. One evening near a music concert venue ten of the taxis blocked a main street, stationary with hazards lights flashing. This was because of a overwhelmed phone network due to the numbers of people at the concert and the cars could not communicate.
One taxi nearly cleaned up a group using a pedestrian crossing. At times they will randomly stop without obvious reason. An emergency vehicle may approach but the cars can't see a safe place to stop and so do not yield.
There is an anti robotaxi activist group that's discovered by placing a traffic cone or road bollard on the bonnet of the car is enough to stop it from moving and the car will sit there with its lights flashing until the object is removed.
All very amusing to me. I'm sure there are lots of online clips to view, which I may well do.
