The comment you failed to make sense of makes a specific correction to a specific false statement. The U.S. does in fact have constitutional protection of privacy. You seem to want to discuss the applicability of that protection to this specific situation. I'm not especially interested in doing that. But I will supply the part of the quote you elided: "transferred to a third party, such as writing on the outside of an envelope sent through the mail or left for pick-up in an area where others might view it" If you want to argue that giving info to the DMV is analagous to writing on the outside of an envelope, feel free. I was only interested in correcting the common misconception that the constitution doesn't say anything about privacy.
