Though one of the image captions says the trailer is designed to cut fuel usage by 5%, I suspect that an open system where trucks could communicate with each other and drive as a 'flock' a group of trucks could have a decent improvement in fuel economy, much like cyclists in a peleton. The trucks could follow VERY closely behind one another in auto mode without the fear of crashing.
