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.
You can see people walking in the path if the car much easier If a small child ran behind the car while reversing I don’t think I’d see them even anywhere near as well as I would if they ran out in front of the car as i was pulling out of the space.
