I think it's a little callous to say they DESERVE to be blindsided. A lot of people get into driving because they don't have any other options. They probably don't have the resources and education to be dialed into what's on the forefront of technology. Have you read this article about how driverless trucks is basically going to decimate the American middle class?

I'm in healthcare tech, and a lot of my low income and middle class patients across the US are truck drivers to support themselves and their families. These people often don't even have internet access or smartphones. I have no idea what these people are going to be able to do for work when this change happens. Most likely they will all apply for and go on disability as that more and more seems to be becoming the new welfare stopgap in the US.
