10+ years ago, I expected that self-driving trucks would be common on US highways by 2025, and self-driving would be having a large effect on the employment of long-haul truckers.
I expected that long-distance trucking would have overtaken passenger cars as the "face" of self-driving vehicles; the thing that people argue about when they argue whether self-driving vehicles are safe enough, good or bad for society, etc. This has not happened. When people argue about self-driving vehicles, they argue about whether they want Waymo cars in their city.
I expected that the trucking industry would shed a lot of workers, replacing them with self-driving trucks that don't need sleep, breaks, or drug testing. I expected that this would be an vivid early example of mass job loss to AI; and in turn that this would motivate more political interest in UBI. This, too, has not happened.
(I certainly did not expect that the trucking industry in 2025 would be much more disrupted by anti-immigrant politics than by self-driving technology.)
The difficulty is mostly about long braking distances requiring impractically large sensing ranges, self-driving cars will certainly be adopted earlier that highway trucks: https://kevinchen.co/blog/autonomous-trucking-harder-than-rideshare
It seems you, at least in 2015, had far more faith than I did and do in Congress's and other government's abilities to update laws to enable new technologies in a timely fashion. If someone had had a roughly complete autonomous truck prototype in 2015, it would have taken 3-5 years to start manufacturing, and 3-10 years more to really scale up and get into customer's plans and procurement processes. It would also be essentially illegal to deploy almost anywhere, and every elected official would know that millions of truckers would hate them if they made any moves to improve the situation. The other side of that equation has a much harder time coordinating around the benefits of automation.
