  The use of millimiter wave (mmWave) for communication and sensing purposes is
one of the functions powered by Next Generation Vehicle-to-Anything (V2X)
networks. The arrival of IEEE~802.11bd, which is able to operate in the 60 GHz
band, opens the doors of Integrated Sensing and Communications (ISAC) to
vehicular networks. Similarly, Radar-based Communications (RadCom) proposes the
use of the radar spectrum for communication puproses. In this paper, we perform
an analysis of the channel capacity for different configurations of RadCom,
showing its potential to offload the V2X spectrum for bumper-to-bumper V2X
applications. We finalize with a discussion on the potential for ISAC from both
the 802.11bd and RadCom approaches.
