Drunken salarymen tottering home after a night’s karaoke are as much a feature of modern Japanas sushi bars and bullet trains. Alcohol consumption is declining in most of the developed world, butnot in Japan, where the number of heavy drinkers has more than doubled in the past 30 years. TheJapanese have traditionally excused such bouts of heavy drinking as the only opportunity repressedworkers have to loosen up. But a horrific incident last year in which a drunk driver killed three youngchildren in Fukuoka has prompted a change of heart.         Toyota is in the vanguard of Japanese firms who want to do something about drunk driving, andmake a bundle for themselves at the same time. It plans to launch a car in 2009 that will shut down theengine if its driver is drunk, using sensors on the steering wheel to measure the alcohol level in thedriver’s sweat. If the driver is wearing gloves, a camera on the dashboard will check for dilated pupils. (adapted from The Economist, February 17th, 2007)
