The human drivers at that intersection resolved the ambiguity the way human drivers always do — through eye contact, through a kind of body language of driving, through the social intelligence that emerges when embodied agents negotiate shared space in real time. No explicit rule prescribed the outcome. The outcome was produced through the exercise of judgment by situated agents who could
