It has a few interesting features.
No turning around at the load or dump site has got to lead to less tire wear, and less road maintenance in those areas, as well as time savings for not turning.
The weight is balanced loaded or empty, so everything from tire and component wear ends up being balanced.
The autonomous trucks tend to be easier on all components and tires anyway, since they have no personality issues, and no desire to be a hot dog. For construction I don't see these catching on, as there are too many changes throughout the day, but in open pits, where the haul is the same, or very nearly so, day after day, I see a real advantage.
The only downside I see at the moment is that the truck drives toward the end of the box that dumps, so if a rock rolls out, it is in the travel path. The other side of that is most hauls are uphill, and rocks rarely roll uphill to fall out.
In areas where wages for relatively low skill positions get too high, the human drivers will price themselves out of a job. I do not see these catching on in the low wage parts of the world.
