These are good jobs, absolutely. However, most people outside the trucking industry have the impression that very soon, most the trucks will be driverless. The long distance truck routes in particular. That assumption may or may not be correct.
They all demonstrate for $15 an hour. Trucking normally pays better than that.
When railroads were first being laid, the legal situation of dead cows and other annoyances had to be resolved first. That was a much simpler time.
I do not believe the legal complications of driverless vehicles will ever be resolved to the point that they can appear on the highways.
