Replace a breathalyzer with something that's less intruisive (like a camera with AI that would observe the person, AI with thermal imaging or air quality sensors, or another possibly-fictional-yet-believable piece of technology) and suddenly, in my eyes, the technology in this thought experiment becomes a no brainer. If there was more of a cultural pressure against drunk driving and actual mechanisms to prevent it that aren't too difficult to maintain and utilize, things like the Daikou services ( https://www.quora.com/How-effective-is-the-Japanese-daikou-service https://www.quora.com/How-effective-is-the-Japanese-daikou-s... ) would pop up and take care of the other logistical problems of getting your car home. And the world would be all the better for it, because of less drunk driving and accidents.
