4) Slow creeping of a vehicle, or start/stop behaviour is an ominous thing. Is the AV about to take off? We don't know. It's clearly confused about something, but what is it going to do? I would like to see an externally obvious decision to be communicated. However it's done. ie: "I am about to drive forward over this fire hose", "I have decided it is safe to pull over", "Does anyone have a problem with that?". "Yell out, or tap once on my side to tell me not to do that". IDK. But these driverless AV's need to be capable of communicating to 'us' and also capable of responding to 'our' communication to them. In real time, not "Please call the number on the side of the vehicle (if there even is one), tell them the location, name & plate number, wait for an operator to help you". Real time. ie: THE CAR, itself.
