My thoughts on the subject...
Drinking & driving has been going on for eons it seems...not gonna change peoples thinking with words or law. Face the reality of it and drive defensively and stay alert. Folks with the 'I never seen it coming' replies after an accident, scare me more than the drunks."I was just minding my business,when outta nowhere..." means the innocent aren't so innocent after-all, you have to know your surroundings at all times, or your just adding to the problem.
Not sticking up for the drinkers, and I don't allow it while underway at anytime or in any vessel. I do drink btw for those interested, but just can't grasp on how it's only someone's Else's fault, it takes two to tangle, and unless your anchored or stopped due to traffic without any possible defensive choice's, IMO is not an accident, it's a failure of your duties of being in total control of your environment.
OK,Thanks for letting me have my say, now if you'll excuse me I should probably go put on my flameproof suit
