There&#x27;s a real possibility that once driverless trucks become widespread, human behavior will change as well.  A very aggressive driver may take advantage of the fact that an automated truck <i>will</i> brake for them, and start routinely cutting off trucks, whereas today they&#x27;d be a little more respectful.  Even pedestrians could start crossing a highway where they shouldn&#x27;t and know they could get away with it.
