I think its definitely an age thing, lots of people 40ish and older think driving drunk isn’t a big deal. Probably because their parents used to do it all the time.
“Well im only putting myself in danger, if I crash then so be it”. People that drive drunk don’t seem to consider the fact they are endangering everyone on the road.
You should always be thinking about how you’re getting home BEFORE the drinking starts. A lot of these guys just don’t plan at all
