Another issue will be piracy.
Stop the truck using a couple of vehicles, cut open the lock on the rear doors, and loot. Pick an isolated stretch of toad, and the pirates will be gone before anyone can respond.

Even for the people willing to use violence, having a human involved opens up unpredictablity and risk. You can't know what's going on in the head of a random trucker, whether they're armed, whether they fancy themselves a cowboy, whatever. It's a high-risk, moderate reward scenario.
In contrast, if you have a system for consistently hitting autonomous trucks, it's a (relatively) low risk, moderate reward crime.
