US car manufacturer General Motors is working on adding augmented reality systems to car windscreens, helping drivers pay attention to particular objects on the road.

The "enhanced vision system", as it's called, is based on a combination of sensors both inside and outside of the car. It can track the position of the car, of the driver's face and eyes, and of objects outside the car. It could alert drivers to traffic or obstacles, and show where the edges of the roads are in dense fog or darkness. 

However, don't get too excited - the technology is still some way off. Thomas Seder, group lab manager for General Motors research and development, told the New York Times that the new system was currently in the research phase, and that he didn’t expect a technology like this to be in the marketplace until at least 2016 or 2018.

By then, we'll all be jetpack-toting robots.
