Automated or “self-driving” vehicles are a future technology rather than one that you’ll find in a dealership tomorrow or in the next few years. A variety of technological hurdles have to be cleared, and other important issues must be addressed before these types of vehicles can be available for sale in the United States.
The Department of Transportation is committed to supporting the innovators who are developing these types of vehicles to ensure their safe testing and deployment before they are available to consumers.
