DUI laws and increased penalties seem to be pretty effective. The number of alcohol-related traffic fatalities dropped from 21,000 to 10,800 between 1981 and 2009, and we have more people driving more miles today. I have no problem with an "annoyance" that saves 10,000 lives a year. http://www.washingtonpost.com/wp-srv/metro/special/fatalities.html
