...pictures of your car & license plate? It's different between writing a person's license plate number down and actually photographing their car, right?
You park your car in a public area, or one viewable from a public area, and you have no reasonable expectation of privacy. They can take all the pictures they wish.
You can sue someone for existing. You can't legitimately sue for taking pictures of anything visible in public. You MAY have a case regarding how they USE the pictures.
Any idiot can sue whoever they want, over any fool thing. But it would be a waste of time and money. There is no reasonable expectation of privacy in anything open to public view. And you don't own the license plate, anyway. The state does.
