I really like all of the ideas. There poses to be two problems.
1. Most people have a gas tank that locks.
2. Committing a criminal act at a place of work is just dumb. The chances of getting caught are higher.
I am thinking...follow her back to her place (stalkerish I know) and have it to do with something there. Like send a lil note, that says something like " this is where you work, this is what you drive, it would be in your best interests to show a little courtesy on the road bc you never know what kind of phyco you piss off. Have a nice day."
Of course you would leave it as a note on the windshield of her car. Maybe with a lil pic of her at work or some shit like that.
Just a thought from my criminal mind.
