Innovations in snowplows

On my morning commute, I saw something that got me excited and that is, the latest innovation in snowplows. The traditional setup is to have a concave blade that can plow straight ahead, plow right or plow left. The new plows have the blade split into two sections each which can be independently angled. What this means is that at a twist of the joystick the blade can change to a "V" shape or the shape of an arrow or one part at a 90 degree angle and the other straight ahead or whatever combination meets the needs of the situation.
