The driverless car will be the beginning of a new frame of mind. We no longer need to labor. Wealth can be shared with everyone because no one has to do the grunt work.
According to the Bureau of Labor Statistics roughly 4,640,000 people were working in the transportation industry in 2014. By 2024 this is supposed to increase to 4.7 million, but why would it increase if we have automation by then? We will have to find another way for those people to contribute to society which will not have to do with labor.
