Parking as such in the picture is asking for trouble and makes you an a$$
While I don't have a really nice car, I still want to take care of it and be dingless. I'm not afraid to walk, so I go as far as possible with no other cars around or spots that have the minimum cars around me (corner spots).
While I hate people that double park near the front because it says "look at me" & "I'm special" -- I will never spit or key a car (even if they deserve it) I've always however wanted to keep a grease pen in the car for such occasions and leave a note on the window... it rubs off, leaves no damage but makes a great point! LOL
I say if you drive some crazy car in which you're too worried to park in the boonies and feel the need to have it close to the entrance and still choose to double park.... well maybe you shouldn't take that car to the faking mall!!!
