At first I thought it must have been malicious, 'cause if you're shitting *on* someone's driveway, that's a deliberate "fuck you!" However, the surveillance video shows her hiding behind the van's door while dropping it on the edge of the street, almost in the gutter, not the driveway... She didn't seem too concerned about hiding her identity, just being the slightest bit modest with a public twosie. So I dunno, just a shameless weirdo too busy or inattentive to make it to a gas station or McDonald's that didn't want to poop their pants. I bet them internet detectives have already figured out who she is and contacted her employer, though.
