I wasn't alive in the 1970's, so I indeed lack that context. However, I'm not arguing against punishment for drunk driving or anything crazy like that, just that it's possible we've passed the ideal point for how much punishment is appropriate for drunk driving. As far as I can tell, the journalist isn't either, just arguing that it should be covered by more generalized offenses rather than ones specific to alcohol. To be honest, that doesn't seem too radical.
