Getting stuck behind a slow-moving truck on a one-lane road is never fun. You can't see what's ahead, you're choking on fumes, and moving at a snail's pace. You could pass the truck, but is there enough room?
Samsung's "Safety Truck" might be the solution. It uses a wireless camera on the truck's front grille, which connects to four displays on the rear of the truck. Vehicles behind the truck can see if another car is approaching (even in the dark), and pass the truck when the coast is clear.
