Personally, I think drunk driving isn't that much of a factor: drinking is a relatively short term kind of planned activity. What I think has a much bigger impact is long term stuff, like the desire to live downtown and/or housing prices (with downtown condos and midtown townhouses being more affordable than big detached homes in burbs) I know families that are rather against the idea of owning a car and arrange housing around that consideration. They prefer to rely more heavily on public transit and the occasional car rental or cab/rideshare.
