The advent of GPS and car navigation apps gave cars a way of communicating with their drivers, keeping them informed where to go and which routes to avoid. In the future, cars might also communicate with one another. Vehicle-to-vehicle communication, or V2V, is a new technology that allows cars to wirelessly share data with each other.
With V2V, cars could one day share vital information like speed and position with surrounding vehicles, making it easier to avoid problems like congestion, reduce the likelihood of dangers like crashes, and potentially improve the environment. In fact, the United States Department of Transportation claims that V2V has the potential to address 80% of multi-vehicle crashes. If certain American legislation passes in 2019, new cars in the US will be required to have V2V as soon as 2023.
