backing in

What's the obsession, the compulsion, with backing in? Go to a large parking lot, say a mall or a superstore, and voila! you are apt to see someone, typically in a big boat of a vehicle, a ponderous and ostentatious truckload of metal and chrome, stopping, pausing, and slowing up the works by doing a K-turn just so they can back into the parking space they have found. Sure, you can accuse me of my own solipsism, posturing an indignant attitude because said drivers are slowing ME, ME, ME. But honestly what's the point? It escapes me. They always seem to want to make a big deal of it, as if to say, "Hey, plebe, look at me. I not only found a space for my metal hull on wheels, I am ready to zip outta here, unlike you, you moron. I'm ready to go. A modern speedster firmly and sure-footedly planted in The Land of the Free and Wait While I Do This." True, no one has ever uttered one syllable expressing such thoughts, but I have a fertile, and febrile, imagination.
