I read recently that some startups are collecting this data and providing it back to police departments. So you could search on a license plate number and receive hits on every where and every time it was used. Of course, it's only available for LE and they have to promise not to talk about where they got the data from. Just imagine a similar system using facial recognition and Google glass/FB/G+/Instagram/etc.
