Gear of Intrigue

So I'm preparing to park at work upon returning from lunch (while still eating a jr. bacon from Wendy's) and accidentally put my car into neutral. And then I realize I've never done that before. Not on purpose, anyways. In what circumstance, apart from towing, would a person use the neutral gear? Let me know. Maybe it's useful and I am driving around, ignoring the coolest part of my car. You never know.

And for now, that's all I have to say.
