Toyota Motor Corp. is developing a fail-safe system for cars that detects drunken drivers and automatically shuts the vehicle down if sensors pick up signs of excessive alcohol consumption.
Cars fitted with the detection system will not start if sweat sensors in the driving wheel detect high levels of alcohol in the driver's bloodstream, according to a report carried by the mass-circulation daily, Asahi Shimbun.
The system could also kick in if the sensors detect abnormal steering, or if a special camera shows that the driver's pupils are not in focus. The car is then slowed to a halt, the report said.
The world's No. 2 automaker hopes to fit cars with the system by the end of 2009, according to the report.
