no, you're the one that's wrong.. with EDM mirrors, I can see BOTH the small side of my car and the immediate lane over next to my carWrong. There is no area that can't be seen between a combination of rear view and the side view mirror. As a car approaches from the rear/side, at the time it can no longer be seen in the rear view it appears in the side view. And when it is no longer seen in the side view, then you'll see it right out your window.
don't talk to me about "that area can't be seen" when you didn't even bother looking at the pics I posted nor experienced what it's like to drive with these kinds of mirrors in a foreign country... the mirrors which provide you a wide field of view from the edge of your car, all the way to the full width of your adjacent lane, which means there's 99% no blind spots
so long as my car is traveling the same parallel path as the other cars, I can always see cars approaching from behind, to next to me, on combination of my mirrors... no cars ever disappears from my non-US mirrors unless I'm approaching traffic in an angle
