It's a good (but wrong) analogy to compare to the "head-up" display on airplanes. However, driving is a 2D experience compared to flying. Pilot would need to pay attention to the surrounding in the 3D world where as driving, pretty much is just in a flat surface (you pay attention to your front, behind, left, right, that's it). I just cannot see the benefit of the HUD display in road driving use. There is no "head-up" necessary in this driving use case.
