People who can't park

You know what bothers me, among other things? Parking space hogs.  You know, the inconsiderate type.  They park on the line or even over it, so you can't get into your vehicle when you come back.  Or even worse, they take up two spaces when there are precious few of them.  

How about those little cars that pull as far into the space as possible.  As you're driving down the aisle you think there's an empty space, but no, it's a matchbox car in there.
