Vehicle-to-vehicle (V2V) communication is a technology that allows cars to exchange information with each other. This system helps vehicles share data about their speed, direction, and location, which can enhance safety on the roads. By communicating, cars can warn each other about potential hazards, such as sudden stops or accidents ahead. V2V technology aims to reduce collisions and improve traffic flow. It is part of a broader movement towards connected vehicles, which also includes vehicle-to-infrastructure (V2I) communication. Together, these technologies can create smarter transportation systems, making driving safer and more efficient for everyone.
