I can see the training and responsibilities shift as things become more automated, but for what a driver costs, I can't see them getting rid of an incab person for otr trips which leave the city. The response time and costs for fixing minor maint like a broken air line would be crazy. Also someone gotta fill those tanks up.
The bulk of the time (= labor costs) from trucking is on the interstates, and as an added perk, this would allow truckers to work 9-5 and stay close to their families rather than being on the road all the time.
I think the future I see is both dumb and terrifying.
I can see this making sense where the driver also has some skilled role at both ends, e.g. supervising loading and unloading of a particular type of cargo. Otherwise it may be just as sensible to build giant truck parking lots at key locations on big highways and have a human board trucks when they get to the closest lot to the final destination. In that model all truck drivers would go home every day, which means it's a less well paid job but also one that's more compatible with having a life outside work - long distance trucking would become something trucks do but drivers don't.
This is inaccurate. If you are sitting in the passenger seat you are classified as "On-Duty Not Driving" You are only 'resting' (aka "Off-Duty") when you are in the bunk.
highway (fully automated truck) <> yard (switch out container/trailer from self-driving truck to manned/normal trucks) <> local (manned)
