That is the largest impact I see, autonomous vehicles taking over driving jobs in the freight industry. And that brings up a question of affect, will the increase in efficiency result in more autonomous delivery vehicles taking to the road or less because they are more efficiency?
I would think that we would see more because the cost of delivery of goods would go down, with that the US would need more energy from fossil fuels and perhaps a need for more workers in the energy industry (coal, oil and gas).
the way I see the trucking industry.....terminals will be built at the city limits....trucks with drivers will move the trucks to the city limits and automatically send the truck down the interstate...no lunch, coffee or toilet breaks
