Vehicle-to-vehicle (V2V) communication is a technology that allows cars to exchange information with each other. This communication helps vehicles share data about their speed, direction, and location, which can improve safety on the roads. For example, if one car detects a sudden stop, it can alert nearby vehicles to prevent accidents. V2V technology aims to enhance traffic management and reduce collisions by providing real-time information. By connecting vehicles, it can also support features like adaptive cruise control and collision avoidance systems, making driving safer and more efficient for everyone on the road.
