I came across an article the other day about a new technology Range Rover has in the works along with a video of it in action. As it stands they only have a few built as prototypes. If this takes off it could be the next big thing for off road vehicles. For a company like Range Rover, who was facing bankruptcy only a few years ago, licensing this could pull them out of the mountain of debt they have.
Basicly its a transparent hood. They've installed cameras under the vehicle which project an image onto a heads up display that spans the length of the dash creating a virtually 100% accurate view of whats occurring under the vehicle.
