  Autonomous vehicles can construct a more accurate perception of their
surrounding environment by exchanging rich sensor data with nearby vehicles.
Such exchange can require larger bandwidths than currently provided by
ITS-G5/DSRC and Cellular V2X. Millimeter wave (mmWave) communications can
provide higher bandwidth and could complement current V2X standards. Recent
studies have started investigating the potential of IEEE 802.11ad to support
high bandwidth vehicular communications. This paper introduces the first
performance evaluation of the IEEE 802.11ad MAC (Medium Access Control) and
beamforming mechanism for mmWave V2V communications. The study highlights
existing opportunities and shortcomings that should guide the development of
mmWave communications for V2V communications.
