Seems like a lot of folks in this thread would call situations like yours "necessary collatoral damage." Some of the stuff I'm reading here is genuinely disgusting, and it makes me uneasy to think I might work with some of the folks espousing it.
I don't see how this is necessary collateral damage for the prevention of drunk driving. I think most folks in this thread would agree that current implementations leave an awful lot to be desired, regardless of what they believe the best approach to be theoretically.
