It totally makes sense with the steering mechanics (assuming you have a normal car that is steered using its front wheels) but if there is a low wall or bollards at the back of the parking space and you don't have sensors or cameras or whatever then you (or at least I) can't easily reverse-park and so entering the parking space involves changing direction about six times, and leaving it involves changing direction about three times.

If there's a narrow parking space with a narrow aisle in front of it then forward-parking is basically impossible so you have to reverse-park, so it's a skill worth having.
