Alcohol and driving do not mix. Drunken drivers are responsible for many a mishap and several unnecessary deaths. Unfortunately many lives are lost day to day due to drivers who have had drinks and yet think they are fit to drive. In India the \"pub city\" Bangalore has the highest incidence of road accidents related to drunken driving and the maximum number of deaths occur on Saturday nights. According to the reports from US National Institute on Alcohol Abuse and Alcoholism: \"In the US in 1995, alcohol-related costs in areas such as crime, health-care, policing and losses in industrial productivity amounted to $167 billion dollars.\"
