If you drive a van with no side windows in the back, and you’re driving along a parking lot row where you have the choice of spots on either the right or left, choose left.
It runs counter to our keep right training, but there’s a good reason for it. When it’s time to back out you’ll be able to see more of what’s behind you in the row. You can see only so much in your mirrors.
Anyway, it works for me. When I remember to do it.
Of course, better still, is parking so you can drive forward out of your parking space—even if it’s the wrong direction for that row.
