> You start by just automating the highway driving, which is a much easier problem than city driving. You might still need the human operator to deal with the off-highway driving at the beginning and end of each journey, but in the middle they can just hang out in the cab and work on their PhD dissertation or whatever. At that point your business has become quite a bit more efficient, because you've gotten rid of the need for your trucks to be stationary for 10 out of every 24 hours. Can't this already be handled in a pony-express fashion? Hand off the trucks between people? Honest question, I assumed that this kind of thing might already be setup. Your solution also requires that a person sit in a single box for 24 hours, I can see that taking a toll, and the start and end of the journey must be timed that a person can sleep at the right time before waking up ready to drive again as the truck needs to come off the highway. I guess my key thoughts are that this doesn't actually lower the human cost (employed for the full time still), and adds on a few extra issues dealing with people. What you gain is a faster overall transport. However, I can see the added automation cost being a lower part of the overall vehicle bill, and there are enough large trucking companies to mean the costs can be spread out over the business.
