There's also the other possibility that it's a firefighter banging on the doors, trying to stop the car from driving into a dangerous area. I'd argue that's the more dangerous scenario too. PCP doesn't magically turn someone into a maniacal killer.
Now that you mention it, this makes me think of all kinds of edge cases and how SDCs should handle them, and how they would detect them... hard problems. Of course, it seems like we humans are requiring the SDCs to be better than we are and not be our equals. I am not sure why. I do not know if that standard is good or bad; just making an observation. For example, a person could be banging on a window screaming for help. Many people would just speed away, some would stop and try to help, and in a few places in this country such aggressive behavior could get the person screaming for help killed.
