I’ve always set my side mirrors so that I could just barely see the side of the car. Somebody sent me this a few weeks ago and I decided to go ahead and try it.
At first it was really uncomfortable looking at my mirrors and not seeing the side of my car. After all, if you can’t see your car, how do you know where you are seeing? But as I got more and more used to it, I realized that I was in fact seeing where I needed to. Go ahead and try it, just give it a little while to get used to before you give up on it. You may spend more time looking over your shoulder in the short run, but not in the long run.
