Volvo showed off a drunken-driving prevention system earlier this year, and aftermarket systems have been used by the courts for some time now, but Toyota’s first foray into the intriguing technology is based on sweat.
That’s right, there are sweat sensors in the steering wheel that can detect the alcohol level in a driver’s bloodstream. If it detects a high-enough level, it will shut down the car completely — we’re assuming before it has started moving. The system would also look for reckless steering and check to see if the driver’s pupils are focusing properly.
Toyota says it will look to add the system in 2009, but we still see these systems as expensive and tricky technology that few, if any, shoppers will opt for until mandated.
