Vehicle-to-Vehicle (V2V) communication is a technology that allows vehicles to exchange information with each other. This communication can include data about speed, location, and direction, helping drivers make safer decisions on the road. By sharing this information, vehicles can alert each other to potential hazards, such as sudden stops or accidents ahead. V2V is part of a broader system known as Vehicle-to-Everything (V2X), which also includes communication with infrastructure like traffic lights and road signs. This technology aims to improve traffic flow, reduce accidents, and enhance overall road safety by creating a connected network of vehicles.
