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.
Takes about the same amount of time as someone backing out when leaving, so it’s balanced out eventually. It’s a little unexpected but I don’t put my car anywhere I’m not 100% sure is safe, and backwards parking isn’t particularly rare, so I’m never really taken aback that much
