A very useful visual to add next to this is "The Most Common Job In Every State"[0] map from NPR's Planet Money. As soon as I was aware of the research in autonomous driving I was pretty confident trucking would be the first industry hit. Until I saw that map I had no sense of how major of a disruption this could be.
