Why does it sound "great"? There's nothing in the original post to support the assertion that "shaming works". This is the question we need to ask:

Are the shaming aspects of this policy effective at preventing drunk driving?

All I see is the humiliation of a public branding. That's "effective" in the sense that "tough on crime" political demagogues can use it to win votes from the brutalized electorate. But shouldn't an engineering community like ours have higher aspirations?

For instance, there is an actual solution to drunk driving on the horizon: self-driving cars.
