What I don't understand about this solution is that if you have full automation on the highways then what you need isn't really remote control for the rest, all you need is to get regulation change so that drivers aren't considered to be driving during autonomous periods. In most of Europe this would mean you could have a driver in the vehicle but they could use the long periods of automated highway driving as their rest time meaning they can travel almost non-stop, as opposed to how they operate at the moment where they are forced to pull over for several hours a day.
