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’m betting it’s the use of the phrase “objectively easier” when that is incorrect by argument of geometry. The “objectively” riles people up.
There is a reason why forklifts have rear-wheel steering (and therefore behave much like an automobile driving in reverse): having the point of rotation towards the direction of motion allows for much more precise maneuvering, much like you would need to do in a larger vehicle trying to fit into a tight parking space.
