I will assume that your question is based on the principle that this is information in the public domain. Licence plates are public, in a sense, because the cars are travelling on public roads. People—the government, but companies too—rely on the public nature of that environment to collect data and then to use them in a way that does not see them as personal information. In that case, the rules on the use and disclosure of that information are more permissive.
