Are you the type of driver that backs into a parking spot? If so, then why? Are you saving the hassle later by wedging yourself into a spot while others wait for you to finish your 3 point turn? Are you trying to prove how good of a driver you are with your skill display? Or is the real reason for a quick getaway for a zombie apocalypse or similar situation?
Why not just find two empty spots and pull through? That way there’s no backing out or in required. Or maybe you are a defensive driver and want to be safe. That’s probably it.
