Adding to sibling (with reference to the difficulty of producing good AR eyesets), the Epson Moverio do work very well. For the purpose of a HUD dashboard quick info - a few big characters (as opposed to, say, pages dense of text) - visibility against environmental light should almost always be given even without darkening "sunglasses" shades (you use the sequence "eyes, displays, shades" when you want to enhance the visibility of the display). So, confirmedly, in case of doubt, the technology is there already.
