V2V, or Vehicle-to-Vehicle communication, is a technology that allows cars to exchange information with each other. This communication can include data about speed, location, and direction, helping vehicles to be aware of their surroundings. The goal of V2V is to enhance road safety and reduce accidents by providing drivers with real-time information about potential hazards. In addition to improving safety, V2V can also contribute to better traffic management. By sharing information about traffic conditions and congestion, vehicles can optimize their routes, leading to reduced travel times and lower emissions. This technology is a key component of the broader V2X (Vehicle-to-Everything) ecosystem, which includes communication with infrastructure and pedestrians.
