And the answer, announced last month by the National Highway Transportation Safety Administration (NHTSA) is 2V . . . or, more precisely, V2V.
V2V technology allows vehicles to communicate with each other and to share important data with the driver. For instance, basic safety data like speed, location and direction of travel are collected from a 360-degree radius, analyzed for risk, and used to warn the driver to take action (like removing a foot from the gas pedal) to avoid common types of crashes like rear-end and intersection collisions.
