From my uninformed point of view, most of those things apply to human drivers as well.

Automated trucks seem appealing because they solve (what appears to me to be) a large problem with human drivers - fatigue and allowable working hours.

Building a fixed-route automated truck seems more doable than a self-driving car that can handle arbitrary roads. I don't know if it's actually any easier, but the problems that need to be solved seem smaller in scope.

I think you trade one complexity (fixed vs variable routes) for many other complexities (larger vehicle with more demands). Think of the complexity of getting a driver license for a passenger sized car vs a commercial driver license, there's a lot more rules (physics and human regulations) around a CDL. So yes, you have a fixed route, but is that really the hard problem to solve, the route to take? Isn't the hard part monitoring road conditions, identifying objects, stopping for emergencies, etc?

Let's say we limit the application to just ISO compliant steel shipping container transport. It seems like we could apply much of the self balancing technology to trailer design to account for various load weights and distributions. Even without some redesign of the trailer, it's not too difficult for me to imagine software being better at controlling the truck than a human. The things that are difficult for humans to learn about driving a truck don't seem all that challenging, especially when given the limited problem space related to what is trying to be achieved with self-driving cars replacing all human transportation in cities.

Fixed route is already solved by trains and trains can be made self-driving or be remoted easily. There is a problem in variable-route, variable-size transport.
