V2V technology allows vehicles to communicate with each other to help avoid crashes. It uses VANETs which create a network for vehicles to share driving data. V2V training covers the benefits of V2V, its history, and the underlying technology. Once fully implemented, V2V is estimated to reduce accidents caused by human error by 70-80% by helping reduce traffic and emissions. Over 1 million vehicles currently have some V2V capability, and analysts predict over 62 million new vehicles will have it by 2023. V2V systems typically include components like inertial navigation, LiDAR, dedicated short-range communications, and GPS receivers.
