Having never heard the term V2X before, a quick search brought me to a wiki page that describes it as the wireless proposals to allow for vehicle-to-'everything' communications that would allow for higher safety and efficiency.

To make it worse there is also a military supplier company named V2X having nothing to do with any of this.

Seems like a very poorly defined acronym.
