That's interesting. How will these cars deal with cases where someone is directing traffic? It's not like these folks use some sort of universal gesture to allow traffic to proceed or to tell them to stop. Sometimes you have police directing traffic, sometimes its construction workers, sometimes it might be utility workers. Sometimes they have the stop-sign-on-a-stick sometimes they don't. In order to avoid excessive delays I wonder if they're going to have to consult the human passenger for advice on whether to proceed? I believe a !significant amount of work has been put into gesture recognition in computer vision research, so maybe this is all moot, but training a NN on gestures seems kind of dangerous in cases where someone uses gestures for stopping/proceeding that are misclassified. I wonder whether there will have to be more machine-readable devices installed along the roadway to help autonomous vehicles? In this case, perhaps a portable traffic control device which provides visual signals and perhaps even RF signals which talk to cars to direct traffic? These devices would be used at accident scenes or construction zones, etc.
