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.
One of those you do everyday. The other you will probably do maybe a couple times a decade.
True, but I find backing in just as easy as backing out. So if backing in has the chance of making my life easier in the case needing a jump start its worth it for me
