My technique is caveman compared to the article, but I habitually roll down the windows before I back out of a parking spot, so I can listen for as well as look for anything that might be in the way. I think I started this after our son was born, born of an increasing mindfulness of kids and their associates (balls, toys, pets.)

In the military, I at some point learned that listening was at least as important as looking. A lot of the senior guys on their 3rd or 4th tour would patrol without a helmet -- it messed with their hearing.

Opening the window a crack is instinctual for me now whenever I first hear a siren on the road, so I can better figure out where it's coming from -- it can give me several extra seconds to plan if and how I need to get out of the way of emergency services. I highly recommend it!

Very good point! I happen to roll down windows every time I start up my car for another reason (the air trapped inside the car while it's parked, probably under sunshine, doesn't feel great to breathe in), but you're totally right that the sound gives a lot more clues than just seeing, when backing out of a spot.

Also helpful in really foggy roads, slow down and roll down windows a little to pick up other vehicles

It sounds crazy but I crack the driver side window anytime I'm not going highway speeds. So much more info about what's going on than being hermetically sealed in a steel tube.
