Project Images on windows and remove side mirrors

Side mirrors surely increases the drag of vehicles so if the technology is possible, we could project images, captured by cameras, on the spots of the side windows where you would look through to see the side mirrors.  But, once automonous cars come along this idea is about useless since we won't need mirrors (that is unless there is a manual override on the car).

Interesting idea. If they could be extended out for trailer towing that would be great.
