This is a Samsung 'Safety Truck', an 18-wheeler with a live feed of what's in front of the truck being displayed on four screens in the rear so you know whether or not you're going to die trying to pass it. Not a bad idea. I'm all for increased road safety, but I'm also all for getting a free 2 x 2 Samsung TV display at home, so I'm torn.
Keep going for a video about the trucks.
Thanks to Melissa, who has her fingers crossed for truckers playing episodes of SpongeBob instead.
