Recently, we reported that the backlash in Japan had caused Nissan to develop a system to prevent drunk-drivers from using their cars. Never one to be left behind, Toyota has released details about it’s own technology, which uses sweat sensors embedded in the steering wheel that detect the amount of blood alcohol content you have. The system may also slow down the car if it detects abnormal steering or if an embedded camera detects that your pupils aren’t in focus. This same camera could also be used for ensuring fatigued driver’s don’t get behind the wheel.
SAAB has also been working on a similar concept, this time using a small breathalyzer device called the AlcoKey. Drivers must register a safe BAC level before the vehicle is wirelessly immobilized. Despite the continued efforts of governments around the world, drivers are still slow to heed the warnings on drink driving.
