With the hours of service reform passed a few years ago, drivers are required to have so many off-duty hours and so many sleep hours per week and day. Being able to go off-duty or log sleep while the truck is traveling means higher fleet velocity, which means higher fleet utilization, which means higher revenue. A truck with a single driver has to sit idle (or off in California) a large part of the day. Capital costs don't take a break during those hours.
