  We are witnessing a transition to a new era where driverless cars will be
pervasively connected to deliver significantly improved safety, traffic
efficiency, and travel experiences. A diverse set of advanced vehicular use
cases including connected autonomous vehicles will be made possible by building
upon the emerging sixth-generation (6G) wireless networks. Among many 6G
wireless technologies, the principal objective of this paper is to introduce
the potential benefits of the hybrid integration of Vehicular Visible Light
Communication (V VLC) and Vehicular Radio Frequency (V RF) communication
systems by studying the impact of interference as well as various
meteorological phenomenon viz. rain, fog and dry snow. In particular, we show
that regardless of any meteorological impact, a properly configured
link-aggregated hybrid V-VLC/V-RF system is capable of meeting stringent ultra
high reliability (>99.999%) and ultra-low latency (<3 ms) requirements, making
it a promising candidate for 6G Vehicle-to-Everything (V2X) Communications. To
stimulate future research in the hybrid RF-VLC V2X space, we also highlight the
potential challenges and research directions.
