Nissan Smart Mirror
 

A nifty use of a high-resolution camera & LCD monitor for a wide & clear rear view - that is not blocked by large head restraints, large boxes, tall passengers, even snow or ice on your rear window and the traditionally large c-pillars/blind spots. You still have the option to convert it back into a regular mirror so you could check the baby seat. Maybe, even maybe you DON'T need the side mirrors?
