To me, it seems objectively easier to pull into a parking space forward and then back out of the space when you are ready to leave. You don’t have to line up with the lines while driving backwards, and it’s easier to keep from hitting other cars as well. So why back in? To me, the only advantage I can think of is that you can get out quicker, technically.
Edit: I do not need driving instruction, just wondered why. The reasoning.
If I’m out at retail I’ll just pull through, but at home I prefer to back into my driveway. My wife’s stupid SUV blocks all sight of the street when I’m getting out of my driveway, so I don’t like backing out of it since I’m blind until it’s almost too late. Backing in to park is the only option and I do it so much I barely think about it. That and we sometimes have kids playing out in the streets in our neighborhood, so I don’t want to take a chance on that.
