Toyota is developing a system for its cars that will allow them to shut down if they detect signs of excessive alcohol consumption by drivers. The system includes sweat sensors in the steering wheel, a camera that checks pupil focus, and a mechanism that detects unsteady steering.
Toyota hopes to offer these features in its 2009 or 2010 models. Another Japanese automaker, Nissan, is also developing anti-drunk-driver devices.
