Nissan has developed a car that can stop drivers from drinking when over the limit. The car uses a combination of electronic “air-sniffers”, a detector which analyses sweat in the hand touching the gearstick and behavioural detectors to determine whether a driver is inebriated. If so, it immobilises itself. The car can differentiate between the driver’s breath and that of passengers. Daily Mail 4/8/07 page 42
