It's kind of ridiculous to be in a place to have to require something like that, like requiring people to wear a helmet so they don't hurt themselves, but as long as it works accurately who cares it should only be a problem if you're ***** up.
Feels like for someone to pull that off you'd either have to be dedicated to being ####### which could get you into worse trouble when you get caught, or whatever workaround there is if it requires you to do it each time you probably aren't going to have as easy of a time doing it when you're not sober.
