Those of you that back your vehicle into parking spots, why do you do it?

I have way more maneuverability backing into a space.

Think of it in terms of circles (well, arcs, really) . If you front park in a space perpendicular to the road, your front wheels make a large circle and your back wheels a smaller one. The parking space needs to be big enough to accommodate the larger circle. If you back into the same space, the larger circle happens on the road.
