Re: Door mirrors...
You mention the lack of 3D vision for such mirror replacements, but Nintendo's 3DS shows that there is a reasonably accessible solution, with up-coming light-field methods possibly offering further improvements shortly. Also, synthetic view multi-camera methods like that shown in recent Land-Rover prototypes may even offer improved visibility around or through obstructions such as pillars.
I had heard before that car door mirrors were responsible for "up to 5%" of a cars drag, so perhaps it would be understandable for vehicle economy concerns to influence regulations shortly.
I think the lack of wing mirrors could actually be a vandalism deterrent and make sharing the roads with cyclists safer. It might even be cheaper. Based on looking at BoMs for phone components a reasonable camera and screen combo might only cost about 20-100$...wonder how the cost of an entire traditional motorised wing-mirror unit compares?
