> one of the things that already exists is autonomous truck caravans, where one driver can "drive" a fleet, of say, 5-10 cars. Trains long predate the truck, and allow a single driver to drive hundreds of cars. But the major advantage of trucks is last-mile logistics - going from the depot where large volumes of cargo pass through to the specific place the cargo is needed. The number of truck drivers, and of future truck attendants, is proportional to the number of stops, not the amount of material being delivered. If anything, removing the bottleneck of requiring a person with a CDL to make a pickup or delivery will cause the number of truck attendants to be much larger than the current number of truck drivers (as already seen for example with Amazon delivery services, UPS trucks, etc).
