I, too, have had friends, friends' family and students die from or killed by drunk driving/drivers. There's no one here advocating drunk driving. I was clearly talking about whether or not any of the present prevention and deterrence efforts are likely to work well, much less likely to work in a way that fits any of our politics. The parallel is clearly the war on drugs, radically misconceived, massively expensive and quite a failure.
You very nicely didn't include the the few easily doable, wholly non-revolutionary, and remarkably cheap ways communities might take this on more effectively as a means of producing fewer tragedies… and save some of the social expenditures Eubulides properly cataloged. I have friends who've been working against the political and cultural grain - armed with remarkably good evidence - for exactly these things in OH and other states, I bet you do, too. They've been beaten back at every turn by people w/o evidence, only the kinds of moral critiques you so clearly attacked jn your interview on consumption a few weeks back.
