found an interesting tidbit from several years back from an individual associated with the UNC school of gov and while the hypothethical event depicted concerns itself w/underage drinking, it addresses the topic at hand as well as a 'gottcha' i didn't consider:
quote: ...that he isn’t required to produce any identification. The officer’s immediate options are limited. The buyer is right that he isn’t required to produce identification. unquote.
a brief discussion of Hiibel v. Sixth Judicial Dist. Court of Nev., 542 U.S. 177 (2004) is included at this point.
quote: A clever officer, though, will take a slightly different approach. Rather than stop the buyer as he leaves the store, the officer will wait until the buyer enters his car and begins to drive away. Then the officer will then conduct a Terry stop. But because it is a vehicular stop, the officer can compel the buyer to produce his license under G.S. 20-29. unquote.

the 'gottcha' is don't climb into your vehicle, at least in NC or you must produce DL.
