I drive/own a propane transport. Someday it might be automated, but the accidents involving the handling of explosive gases will be spectacular during the transition.
Some tasks require more sensors and handshakes between systems than the human costs in the long run.
Not to mention maneuvering a 53’ trailer which is essentially a bomb into places like orchards or small retail locations.
Line haul of freight? No problem! Bulk hazmat? No way.
I think semis will be the last thing automated because back them up is so tough. Although it could easily wind up that the human driver is just there for final delivery and gets to be a passenger the rest of the time.
