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.
I work for a bank and we need a clear view of each other when we open the building, so we all back into our parking spaces. At first it was tricky and took some practice, but after a few tries you get so used to it becomes more intuitive to park that way. And it’s so much easier to leave without having to yield to cars and pedestrians passing by as you’re trying to back out.
