Interesting, but does every unit have a driver? I was thinking, it could be interesting that they all have their drivers, because finally they won't all go to the same destination.
So it would be great that as a truck driver, you could attach yourself to one of these trains, sleep for a couple of hundred miles, put the alarm clock, wake up, then detach at the right time and go to your final individual destination. Maybe even take another "road train" for another couple of hundred miles...
