Hahah, Newby should lol at this. He was with me once when I parked backwards at my friend's house, and upon leaving in my friend's car, I was informed by his neighbor that I was parked illegally. I said I'd be back in a few, and that I'm not worried about it. Came back ~90 mins later, and he was still standing there, staring at my car, now with another neighbor out on the other side of the street looking at it.
neighbor 1:"If you had left it there for 24 hours, It would have been towed."
neighbor 2: *glare*
me: "Well, I'm in luck, becuase I'm leaving."
I always park backward when it's more convenient. It doesn't cause problems.
