I agree. I think this concept works in a hybrid form. Most travel routes are well maintained, clearly pained and signed. I've been toying with the idea of having automated trucks to do the long distance hauls between checkpoints outside of cities where a driver will pick up the auto truck and take it into the city. Eliminate man hours, and the isolation of cross country truck driving. Drivers can actually have lives. But yeah I've no money or contacts to even start that. My point is, I think the concept is completely viable in a more hybrid model.
