You can fit in way smaller spaces when backing in. Once you get the knack for it it’s not really harder than going in forwards either.

protip: look in your side mirrors and pretend it’s a video screen. if you want to go left steer left, if you want to go right steer right. Don’t even start thinking about “It’s on the left in the mirror so on the right in real life, but it’s backwards so…” or you’ll have a bad time.
