Mercedes Is Making a Self-Driving Semi to Change the Future of Shipping (wired.com)

Mercedes is making good strides with driverless vehicles but they should make sure to take have precautionary measures in place for driver's that could be reckless.

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.

A self-driving semi will save almost enough on driver salaries to pay for its fuel consumption.
