That person who has to park their 1993 Mercury Grand Marquis diagonally because they don't want it to get dinged. 

The idiot in the luxury car who feels he owns both spaces by virtue of how much he spent on his ride.

The woman who can't for the life of her come to the realization that if she parks 6 inches away from your driver's door, you can't get in your car.

For all of these people, there is a website where you can print out your own ticket to let them know just how much of a blight on the face of humanity they are.
