The real issue is why are bars legal in the first place? Not being a user of alcohol but living next to a bar I constantly ask that question. If they really wanted to catch drunk drivers just sit in front of my house and you would pick up a couple an hour.
Also how can you call yourself a adult and then go out get completely shitfaced then go "Oh no, I don't have a way to get home." like it was a unavoidable consequence of existence.
