You're probably tired of reading that the Internet of Things is the hottest thing going, and that IoT is a boon to technology and, simultaneously, a potential disaster for security and privacy. However, over the past few years, another IoT-related technology has been growing: vehicle to vehicle.
V2V is a way for automobiles to communicate directly with other vehicles on the road. Vehicles communicating with stationary checkpoints positioned along roadways sometimes is referred to as "vehicle to infrastructure," or V2I.
The National Highway Traffic and Safety Association sees V2V as a way for "vehicles ranging from cars to trucks and buses to trains" to relay safety and mobility information.
