I think simply getting a class A is a great investment. Most people think the trucking industry is just long haul freight runs but you need a class A for lots of jobs that at least pay decently. Driving cement mixers hauling crushed rock for construction sites. And plenty of in town deliveries especially if you are in a major metropolitan area. Agree with OP that true full complete automation is still a ways off maybe for over the road on interstates but when you get close to a city they’ll want a human to take over. Definitely a good gig. I have a class A license being an apprentice lineman and have to drive around poles and small cranes.
