I used to own an OTR trucking company. The biggest issue for us other than finding drivers like the article mentions were the FMSCA regulations around the duration a driver is permitted to drive on a given day. We would be forced to stop a few miles short of a dropoff location because the driver ran out of driving time and was forced to enter the sleeping berth to rest. Companies like Amazon solve for this by driving in teams of two per truck so you can swap drivers, but finding even a single driver for us was a challenge. I'm curious what the current state of regulations say for autonomous trucks. If they are not capped on drive time then that alone would be a huge win for companies.
