Anyone who has had to look down at a center console or smart phone to decipher their next turn will appreciate the convenience of having precise instructions superimposed on the road itself. A driver who is using Head-Up Display to get directions will see an indication for the turn lane they need to be in overlaid on the lane itself.

Decreased visibility

Head-Up Displays paired with infrared cameras can give drivers crucial information in low visibility circumstances such as fog. The systems can project, in real-time, the lines of the road and even cars ahead onto the windshield so that drivers are safely aware of what’s around them.

Connectivity

Head-Up Display can pair with Bluetooth or cell phones to allow for hands free texting and dialing. Future functions could include displaying information from applications, such as a restaurant's Yelp rating, in the driver's field of vision.

In 2014, auto manufacturers offered Head-Up Display technology in 38 different models (primarily Audi, BMW, Cadillac and Lexus) reflecting growing demand among consumers. Cost is still an issue—HUD displays require specially treated windshields and pricey optical equipment. For now, the majority of HUD-enabled vehicles are luxury models and the units can add a few thousand dollars to the MSRP of the vehicle.
