DUI is an offense which is not restricted by socio-economic class, ethnicity, age or gender. It can "happen" to anyone who drinks and miscalculates how much he or she had to drink, or those who know they are drunk, but nevertheless decide to take the risk. Usual excuses include "my place is just a mile away" or "it's too cold to walk," or "there are no cabs because it's a home football weekend" or "I need my car first thing in the morning to go to work" or "I've been drinking for 20 years and weigh 250 pounds, so I can handle more than most people" or "I am (insert ethnic group known for drinking, all Germanic, Slavic and Celtic peoples fit the bill), so my genes allow me to drink more than other people." And of course, all of these people will drive slowly and carefully to compensate for their condition, because the people who get DUIs are not just drunk, but driving carelessly. Or at least that is what they tell themselves. This rationalization process is what leads otherwise responsible, law-abiding people to get behind the wheel after drinking. Thus, DUI is a crime, which is not the exclusive domain of hardened criminals and bad asses.
