As a minimum the government's role would be similar to its existing role in regulation of aircraft systems, interfaces between aircraft and ground systems, etc. An automated vehicle control system would involve extensive technology in areas where the U.S. has a lead such as computers, networks, software, and aircraft-type systems. If the U.S. took a lead role in developing vehicle automation technology and associated standards, procedures, techniques, and regulations it could be expected to lead the world in vehicle automation in a manner similar to the experience with aviation. However, the same issues apply to credit cards, cell phones, and other modern technology and have not apparently inhibited deployment or use of these systems. Passenger aircraft still have pilots.
Subways still have drivers.
Near term guidance systems will aid and support drivers in a manner similar to the existing aircraft systems. Indeed, one of the most interesting and complex questions to be answered is how to design the interfaces between the automation systems and the drivers for best human engineering. Early automation systems will probably only accomplish part of the guidance solution. Such a relatively simple system could achieve increased vehicle density and highway capacity while relieving drivers of considerable traffic stress.
