What is "vehicle-to-everything"

Vehicle-to-everything (V2X) communication is the passing of information from a vehicle to any entity that may affect the vehicle, and viceversa. It is a vehicular communication system that incorporates other more specific types of communication as V2I (Vehicle-to-Infrastructure), V2V ( Vehicle-to-vehicle), V2P (Vehicle-to-Pedestrian), V2D ( Vehicle-to-device) and V2G ( Vehicle-to-grid).

The main push for V2X is safety, with energy savings also being important. However, there are still obstacles preventing the roll-out of this technology, mainly legal issues and the fact that, unless almost the totality of the existing vehicles adopt it, its effectiveness is rather limited.
