Just follow the yellow brick road ... thin red cable and you know where to go! Instead of looking at a small 6 inch screen, or listening to less than exact turn by turn directions, Virtual Cable provides you with a red ribbon projected on your windshield showing the exact path you should be taking. The ribbon actually appears to exist in 3D space outside your car thanks to a patent pending volumetric display system using lasers and mirrors.
