That's a non-sequitur, mentions an issue and skips over how this is going to work. I already heard about existing systems failing if you have too many drunk people in the car. I don't see how that can be avoided with an ambient air sensor. Especially in the extreme "I'm getting drunk by breathing the air you exhale" situations.
