Possible futures for fully automated vehicles : using scenario planning and system dynamics to grapple with uncertainty
It is widely expected that fully automated vehicles (also commonly referred to as "driverless" or "self-driving" cars) will significantly change transportation systems in the United States and around the world. By reducing or eliminating many of the costs and disincentives of travel by automobile, …
