Things I Don't Understand, Part I

One thing I don’t understand is why people back into parking spaces. My only guess is that they figure it will be quicker when they want to leave.

I had an example today. I drove into the parking deck here on campus, and pulled forward into a space. There had been a car well ahead of me when I entered, and the person was backing into a space. Back, forward, a little sideways, forward, back, multiple times trying to get straight. I had already parked and was walking well away from him or her before they finished. So the entire effort had wasted a lot of time, and I really doubt they will ultimately get out too much faster than me, even though I will have to back out when I leave.
