That matrix mirror won't work in ie dirty cars, and as something seemingly complex and expensive, no manufacturer would put it willingly and most buyers wouldn't pay up for it neither. You would have to enforce this via regulators. Good luck pushing such thing in nimby-ridden US (for lack of better expression). How about other approach - trying to foster a culture amongst people of not being an a-hole to others, especially on the roads? Rather than playing whack-a-mole with all possible variants how assholism can be manifested. It generally works quite well in western Europe, I can't remember the last time somebody blinded me (if I don't count split-second situations of popping up suddenly from behind some tight curve).
