Take for example autonomous driving. In this scenario multiple autonomous vehicles need to coordinate with each other to prevent collisions. A concrete example would be zip-merging, as both vehicles, the one in the lane and the other trying to merge into it, need to coordinate their respective velocities to accomplish this maneuver safely.
