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.
Zero traffic would mean it’s an empty lot. If there’s a curb or cement blocks preventing pull through, I’d still back into a spot.
But to answer the spirit of your question, it’s easier to back in to a confined spot due to the steering being on the “back” side and ability to use the side mirrors to line it up. Other than pull through spots, I can’t think of a single good reason to pull in to a parking spot forwards rather than back in.
I agree it can be easier. I prefer it if the spot I am backing into is tight. When I say zero traffic I should clarify to mean it is very unlikely to have another vehicle in motion within your yard when you are parking/leaving.
