Yep, I always thought that driverless trucks will come before that kind of cars. Better safety, lower costs, faster shipping, because there are no driver breaks.
Maybe we went through something similar when digging machines replaced people with shovels.
The main difference is instead of requiring the coveted commercial drivers license plus or minus hazmat certs, you'll have a grunt laborer who optimistically knows how to count in english and can handle a pallet jack and/or electric forklift.
