A transparent truck can allow cars to pass safely. Video screens on the back of the big rig show the view from a camera on the truck's front bumper. Samsung outfitted an 18 wheeler, dubbed The Safety Truck, with TVs mounted on the rear trailer doors.  A live image from the front-view camera lets following drivers know when it’s safe to overtake the truck. In this podcast, Dan Clark describes Samsung’s test in Argentina. The truck is not expected in the US anytime soon, but there is always hope.
