Reminds me of the incident in February where a waymo tried to get through a bunch of street revelers, and their response was to set it on fire. From the old pcmag story :

San Francisco Fire Chief Jeanine Nicholson noted that it had tallied 55 incidents where self-driving vehicles had interfered with rescue operations in the city.

In some cases, residents have put orange cones on the hoods of cars, which makes them temporarily immobile.
