Agree with Airborn's reply. For years, I had my side mirrors adjusted to (just barely) see the left or right side of my car. After reading a few articles about how to properly adjust my side mirrors, in line with my rear view mirror, I changed. I'm of course not alone. 100% of the people I know do EXACTLY what I did for years. It takes a while to get used to but when you adjust the mirrors properly, you eliminte blind spots in your rear view.
