Two of the most important parts of driving are being able to see well and knowing where you're going. Head-up display technology works with both of those ideas in mind -- and it's going to change the way we see the road forever.

The days of looking away from the road, missing a turn because you didn't understand the GPS or driving blind in the fog may soon be a thing of the past.

Heads-up display (HUD) systems can project information on the windshield, tell you where to turn, notify you of lane markings, identify how close the car in front of you is and even give you restaurant information all right in front of your eyes -- and while you're actually able to see those objects or places.

Believe it or not -- and yes, you should believe it -- head-up displays are not a new technology.
