It just occurred to me - there is another (albeit more risky) way to go about this one.
Call her out on parking there so she gets a ticket. Before she finds out, see if you can have her notified on command. Then arrive at her car well before she gets outside to check on said ticket, and douse the car in gasoline. Greet her about 5 feet in front of her car, smoking a cigarette. When you see her say, "What we've got here is...failure to communicate." Then flick the cigarette over your head to the car, while walking in slow-motion towards her.
Biggity Bam - karma in action.
