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.
That was my point. With how tight European car parks are it’s damn near impossible to get to the storage area if you park the wrong way around. Potential damage trying is why I won’t park anywhere near someone who’s parked nose out.
