Volvo Alcoguard (video)

According to Volvo safety officials, one in every three traffic fatalities in Europe is alcohol-related. To help reduce this number, Volvo has developed 'Alcoguard', which uses fuel-cell technology to accurately read a person's blood alcohol level. In order to start a vehicle, the driver must blow into a wireless hand-held unit. If his/her blood alcohol level is higher than 0.2 g/l, the car will not start. Volvo hopes this technology will help lead to a change in the general attitude towards drinking and driving, resulting in the elimination of alcohol-related road accidents and deaths.
