Vehicle-to-Vehicle Communication (V2V) is a technology that allows vehicles to communicate with each other to enhance safety and efficiency on the roads. By sharing information about speed, location, and direction, vehicles can warn each other of potential hazards, such as sudden stops or accidents, thereby reducing the risk of collisions. This communication occurs through wireless networks, enabling real-time data exchange. V2V is a crucial component of the broader concept of Connected Vehicles, which aims to create a safer and more efficient transportation system. As this technology evolves, it holds the promise of transforming how we drive and interact with our vehicles.
