It is a matter of time before they reflect everything off the windscreen in the manner of a heads up display. I have been waiting for this and would welcome it. Never take your eyes off the road and no excuse to miss your speed etc?
The issue I have found to making this work has been using input or gesture to interact with it, it's clunky would be polite. The current crop of luxo-barge (7 Series etc) already have gesture control with the touchscreen however it is more variable than valuable from my experience. The same is true of using it in computer environments so far. I have tried several of the options and found them to be blunt even after repeated training and practice (3 months with one) The good news is that all the engineering going into assisted reality and virtual reality will probably benefit this moving forwards.
The current move to glass cockpits in cars with no buttons feels like it is a little too fast but then the art of selling new cars is to have something the old one did not and then cause a trade-up. A little like phones. 1 more pixel on the camera, new colour, different charger socket, tweak of the software. They want you to buy the newest one not a secondhand one. Interestingly the trade seems to want you to buy the second hand one as there is more margin in it.
