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 find it easier to backwards park, especially in tighter spaces. Mostly because it’s easier if you look properly and watch your mirrors and don’t rush. It’s also easier to leave because you’ve got better line of sight for oncoming traffic
