How to eliminate driving blind spots by readjusting your mirror:
For years, we’d been setting our side-view mirrors so that they gave us a view of the back corner of our cars. This is the way it’s been done for generations – from grandfather, to father, to us! But we finally discovered something very interesting. The back corner of the car never moves. It always stays in the same exact place. So there’s really no reason to keep an eye on it.
By moving the side mirrors farther out, you can line up all three of your mirrors so they have minimal overlap — and you can see everything behind you and beside you.
