I’m going to add one of those circular concave / convex (sorry I can never remember which it is) mirrors to the drivers side mirror to help improve the blind spot on the drivers side.
My question is do I mount it closer to the vehicle (right side of drivers side mirror) or further away from the vehicle (left side of drivers side mirror)
