Attitudes on drinking and driving have changed. Behold a 1984 op ed in the NY Times titled Drinking and Driving Can Mix.
First 3 paragraphs:
LAST Saturday night I drove home drunk or almost certainly that would have been the indication from any breath or blood test that I might have been required to take. I drove home drunk the Saturday before that, too, and the one before that, and the one before that, in what probably amounts to a fairly consistent pattern over the last 25 years, ever since I have been licensed to drive.
During those 25 years, I have never had an accident, nor have I ever been issued a summons for driving while intoxicated or impaired. This is not to suggest that I encourage weekend intemperance, or intemperance at any time, for that matter. Neither do I wish to extol my own driving ability, nor to say that somehow I've been leading a charmed life, because what happens to be true for me applies no less to nearly all of my friends.
Indeed, I would venture to extend that to include the vast majority of those whose life styles are in general similar to mine; namely, to all who regularly socialize with family, friends and neighbors, at cocktail or dinner parties, in private homes, restaurants, clubs or any other place where alcoholic beverages are customarily served. At the end of any particular evening, most of those who have engaged in such activities undoubtedly have in their bloodstreams a measure of alcohol above the minimum percentage established by the state beyond which one may be considered intoxicated or impaired, or, to put it bluntly, drunk. Yet these people almost invariably drive home safely without incident, accident or arrest - just as I do.

37 years later this argument hasn't aged very well
in other countries the adjustment has come much later...only 15 years ago the restaurant business in France was up in arms that the French police were killing their business because they had started to enforce laws against drunk driving...there were actually demonstrations against this newest form of tyranny...of course all it takes is a warm breeze to get the French to gather in protest...but the restauranteurs had a point...the new enforcement policy did hurt their businesses
