driverless rig driverless rigA semi-trailer truck (tractor trailer) that is driverless from the start of the trip to the end. On the highway, the driverless rig is autonomous; however, when it travels on city and side roads, it is driven from a central station by remote drivers with computer screens. Driverless rigs are expected to become mainstream by 2020 and thereafter. How many of the nearly 1.7 million truck drivers in the U.S. will be retrained as drivers at a computer terminal remains to be seen. See driverless car. |
