This is totally cool! New technology developed by Samsung Corporation. When attempting to overtake a Samsung truck, the built-in wireless camera at the front of the truck allows you to see oncoming vehicles on a large screen behind the truck.
Watch this video and you'll see what I mean. For bigger market, they should make this available and installable to all buses and trucks; not just Samsung trucks. Yea, Samsung pioneered this one but I predict, buses manufacturers will start incorporating such technology in their buses as well.
