  The vehicular ad hoc networks (VANETs) have been researched for over twenty
years. Although being a fundamental communication approach for vehicles, the
conventional VANETs are challenged by the newly emerged autonomous vehicles
(AVs) which introduce new features and challenges on communications. In the
meantime, with the recent advances of artificial intelligence and 5G cellular
networks, how should the fundamental framework of VANET evolve to utilize the
new technologies? In this article, we reconsider the problem of
vehicle-to-vehicle communications when the network is composed of AVs. We
discuss the features and specific demands of AVs and how the conventional
VANETs should adapt to fit them.
