There are supplementary mirrors, with adhesive backing, available to put on the side mirrors of a car, to improve the view.
I have heard several different and contradictory opinions:

[li]Put the convex mirror on the lower inside corner of the side mirror.[/li][li]Put the convex mirror on the lower outside corner of the side mirror.[/li][li]I have also heard a version advising to put the mirrors in the trunk of one’s car, stay home, & have a beer, but we shall ignore that one.[/li][/ol]
Since Versions #1 and #2 seem to have an equal number of adherents, I’m guessing that their advice isn’t well-informed.
Put it on such that it solves a blind spot problem, but allows you to use the less-convex or non-convex mirror you already have to effectively see down the road and curbs and such.
So you know, on my Ram truck, the standard passenger side mirror in standard non-towing position has the convex part farthest from the driver and a standard non-convex mirror closest. When towing, the mirrors flip such that the convex part is on top, and the non-convex part is on the bottom. This is okay, because it widens the view of both… but if you are just slapping a round one onto a current setup, the…
It rarely makes sense to put the convex part closest to the driver… as a greater % of it will just reflect the side of the car/vehicle/whatever.
I live by my mirrors to tow a variety of boats, etc… so, convex should be farthest from you in most applications… or you’ll just reflect big chunks of your car door…
My brand-new 2012 Ford Mustang came with small convex mirrors pre-installed on the side mirrors. They’re in the outside lower corners, for what that’s worth.
I just had to replace mine. Used one for years. It is a “wedge” type rather than the circular form. So placement on the mirror has no real affect on what is visible in the wedge mirror. I put in in the lower inside since that part usually shows a bit of car side and some pavement. Further out it would block more of the interesting stuff to the left rear.
