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 mostly pulling forward. Sometimes there is a smaller and packed parking lot, where the turn radius of my vehicle will not make it into a spot going forward. It could be done but I’d have to spend an extra 10 min to Austin powers my way into a spot going forward and then do it again backing out. In cases like that I find it much easier to have the turning point of my vehicle in the drive lane so I can have a better swing to line myself up and back in. It’s just better for everyone in that scenario.
