Self driving trucks probably are going to be considered a national security issue going forward. We can't have cargo sitting around waiting for humans in a health crisis. That will indeed be a huge gut punch to that segment of the labor market. The only slightly silver lining is that trucking has very high turnover so the number put out of their jobs will be less than you might think. What will hurt though will be the loss of opportunity to be a truck driver, even if only for a few years.
