Here’s a great safety hack I picked up recently: adjust your car mirrors to capture more of the blind spots. From the authors:
“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.
