There is a website that tracks flock cameras.

It would be interesting to train an image recognition algorithm on detecting flock cameras

Or just query nearby bluetooth devices:

EDIT: Also, those things read bumper stickers in addition to license plates. I've often wondered if they check for injection attacks between character recognition and storing it in their database.

Another edit: An attacker wouldn't even need to put the sticker on their own vehicle. And a $20 thermal receipt printer (a "cat printer" as they're known because the most popular model has cat ears and a cute cat face on it) can print on rolls of adhesive paper. I honestly wonder why no one uses them for sticker-based graffiti already. Probably because thermal prints don't last long in sunlight.

Reminds me of a Cory Doctorow story.
