This is a clever idea, but unfortunately, this wouldn't work. The IR rays will hit the entire windshield and just make the whole thing glow. To understand why, imagine what the view would be from different seats in the car. For the driver to see an object, such as a tree, the windshield would have to glow in the location where the driver should see the tree. But for a passenger, the windshield would have to glow in a different location for him to see the same tree in the correct apparent place. The location for the tree would be in a different place on the windshield for every view point in the car. In fact, the IR rays from the tree will hit the entire windshield evenly, producing an even glow. The same will be true for every object in front of the IR lights.

To make an image you need some kind of lens, like a camera. The lens creates the effect of having only one point of view. It would be pretty hard to make this work on a windshield.
