Whether or not it is a menace, I am really surprised that you're implicitly taking a "drunk driving is worthy of social control" position - and that you passively indicate that you don't know whether current enforcement/prevention is effective. Everything you've ever written, here, about the means of social control practiced by modern day police, courts, and prisons - and everything you've written about the contradictions of work and family in todays world - would seemingly point in the direction of there being no possible way, however much a real threat to public safety drunk driving is, that contemporary enforcement/prevention is effective.
Are any of the solutions likely to be doing anything about the everyday psychic pain people feel, pain they suppress with drugs and alcohol? Are any of the solutions being proposed doing anything to increase the number of local drinking establishments near where people live so they don't have to drive after drinking? There are public programs to pay for taxis to take people home in some places but not, as far as I know, in any college town. Anyone know about large cities where such a program exists (I may have missed a post that addressed this.) Are any of the solutions being proposed focused on increasing alternative opportunities for youthful entertainment other than drinking? I know that nowhere in Michigan is that the case, and in many places in Michigan public programs that used to provide opportunities for alternative activities have been among the first things to go when fiscal problems emerge.
Given all the things you've written about the class, race, etc. can you imagine any way in which enforcement is class, race or gender neutral? I can't imagine how bankrupting someone and leaving them with a felony record (given what that means these days) serves as a viable enforcement/prevention method relative to drunk driving.
