I don't know whether you're a woman or a man, but let's say you're a woman. You know your husband goes to work everyday, you know his car, you know his licence plate and you know where he works.

Now, you see a picture on the internet, like a disco bar, or a penthouse. And you see, in the parking lot, some vehicles, being your husband's among them. Now what?

Or the other way, your husband sees your car at an expensive beauty shop, instead of being at a hospital, because you said you were visiting your dying relative.

Privacy must be protected, it's a very important thing in European countries, and licence plates belong to that privacy, as well as phone numbers.
