  Vehicles will not only get more and more automated, but they will also
cooperate in new ways. Currently, human-driven vehicles begin to communicate
with each other using vehicle-to-everything technology. Future vehicles will
use communication to share sensor data and even negotiate cooperative
maneuvers. This lets them learn more about the environment and improves traffic
flow and passenger comfort as more predictable maneuvers are likely to lead to
a smoother ride. This paper introduces the most important concepts around
cooperative vehicular maneuvers. We also summarize currently open challenges
and questions to answer before a deployment can begin. Afterward, we give some
perspectives on the further evolution of cooperative maneuvers and beyond.
