Automated trucking would be cool to see in my lifetime, but to be honest the idea makes me really uncomfortable because it would put roughly two million people out of work.
It's not just truckers, but forklift drivers, cab drivers, nurse assistants, any other job that can be replaced by a robot. There should never be a situation where we are putting people to work or putting people in danger for no reason other than so we feel comfortable paying them to do poorly what a robot can do perfectly.
