According to this article in Mashable, Samsung has come up with a really cool solution to this problem. The Safety Truck is a semi with a camera mounted on the front that shows the road ahead on a screen mounted to the back of the truck. The move is a part of an effort to reduce head-on collisions from passing.
In addition to making passing safer, Samsung says that this would let drivers see any obstacles in the road ahead, preventing the need for sudden emergency braking.
You won't see these trucks on the road anytime soon unfortunately; Samsung says it's still fine tuning the technology involved.
