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.
Have you ever seen a forklift? Ever noticed that it steers with the back wheels? That’s because it’s easier to maneuver at low speeds, in tight spots, with rear wheel steering. Since you’re driving backwards, you’re giving yourself rear wheel steering.
