Phantom Car

Microsoft just filed a patent for an application that would replace how-to-reach-X instructions.

Instead of studying an on-screen map or listening to spoken instructions, the system lets a driver pursue a cartoon car projected onto the windscreen in front of them. The navigation system checks a car’s location and calculates a route in the usual way, but the driver follows the ghost car as if it were the leader of a convoy.

Can't say I don't want that for my car.
