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.
If you have the time and space to back in when you’re parking it can make leaving easier. Invest a little time now to make things easier later.
I wouldn’t make people wait on me to back in though unless there was some important reason to back in.
I get incredible satisfaction when I back into a parking spot at my local Sam’s Club where cars are constantly coming in and going. Watching my neighbor in the parking lot struggle to back out is hilarious.
