A headlight projector

Taking the eyes off the road is the most common cause for traffic accidents. So why don’t we change the in-car display to an on-road display? And while we’re at it, place a depth camera (a Kinect, basically) next to the projector and just don’t show anything if we’re in a dangerous situation? And while we’re still at it, let’s place a projector on the back of the car telling your drivers where you’re going and let them turn off their navigation and just follow you.
