From my understanding, public transport in America tends to be really bad or non-existent in many cities and the walkways tend to be underdeveloped, essentially forcing people to drive even in situations when it's considered the worst option in other countries. In turn that's the main culprit behind why people would be willing to get behind the wheel while drunk, instead of just taking the bus home. From TV shows I know of "designated drivers", essentially someone comes with the group drinking and stays sober so that they can get home later, something unheard of here in Stockholm as everyone just hops on the metro and/or the bus.

Is that it? Am I correct about what the primary reason for drunk driving is in the US?
