Diameter of my mirrors is 3 inch. I would not even think putting that small mirrors to my car unless they are convex. With those there is about 2.5-3 meter blind spot behind b-pillar but bacause most cars are over 3 meters there isnt any in motorway speeds. Manufacturing costs for one mirror will be about 25€.
