To paraphrase CarSpace member Lateralg, your car’s rear quarter panels aren’t a threat. Why should you be looking at them in your side view mirrors then? If you are like most drivers, you are still aligning your side mirrors the “old” way.
A better way to adjust your side mirrors is to move the glass outwards so your field of view is of other cars and blind spots are eliminated.
To adjust your side mirrors the Zen way, first put your head against the driver’s side window. Adjust the mirror so the rear quarter panel just barely disappears from your field of view. Then move your head towards the center of the car – your console or gear selector is a good reference point to hover over if you have one.
Repeat the adjustment for the right side mirror so that your right rear quarter panel just disappears from your field of view.
This new arrangement will take a short while to get used to. If it absolutely drives you crazy, then move the mirrors in just a touch so that you can just barely see your rear quarter panels when you look at your mirrors.
But a true Zen mirror master will no longer have any blind spots, will have more awareness of cars on either side of the vehicle and will thus see deeply . And maybe that’ll help keep others from dinging your rear quarter panels (not that you’ll ever look at them again anyway).
