Taking a photograph of a car with its license plate is legal. As is selling a photo you've taken, whether it has a license plate or not.
Therefore taking millions of photos in public of cars, and turning their license plate numbers into a database is legal, as is selling that information. It's all data gained in public.
Obviously it's now scary that you're being tracked. But what is the solution? We certainly don't want to outlaw taking photos in public. Is it the mass aggregation of already-public data that should be made illegal? What adverse consequences might that have, e.g. journalists compiling public data to prove governmental corruption?
