> Ultimately, self-driving vehicles require maintenance on the road, meaning a human riding along; if the self-driving capability fails, the human will take over the wheel. Maybe in the first several years. After that the technology will mature and maintenance won't be needed that often. And if there is a problem the truck can stop at the roadside, like in case of a failure today, and call for help. I guess logistics companies will keep teams on the road which can respond quickly if a self driving truck has problems.
