It may seem obvious that a major consequence of self-driving trucks would be a lot of unemployed truck drivers, but the reality -- at least for those who drive tractor trailers -- could be better jobs. Autonomous vehicles have massive potential benefits. Models suggest that in the U.S. alone, between 30 thousand and 40 thousand lives would be saved annually -- for perspective, about 3 thousand died on 9/11. There will be some job losses, and adjustments will need to be made.
