Almost all the neighbors across from me back into their spaces. I find it annoying when I am coming home and have to wait for them to maneuver their giant SUVs into a small space before I can park on my side of the street. I have never seen the point. It is much harder to back in than to back out, and it takes longer, so why does someone do it? Edit: I guess I am really talking about perpendicular spaces, where your front (or back) wheels are supposed to touch the curb, rather than parallel where your passenger side wheels are to the curb. The third option would be diagonal, which it would be really challenging to back into.
