There wasn't yet a moral vocabulary around what happened when an impaired driver killed someone with their car. Judges in the 19 thirties rarely sent people to jail for drunk driving. Prosecutors rarely filed charges. The police officer who caught you drunk iving knew that the likelihood of anything happening was so low it was pointless for him to even arrest you. In 19 39, the american medical association put out guide lines on drunk driving and said that the threshold for criminal conviction should be point one five. Right now, most rican states have a threshold of half that. It is like putting a gun in your pocket if you want to get a sense of how strange attitudes were towards drunk driving in
