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.
Definitely an interesting idea! It's great to see a major car company being pro-active when it comes to drunk drivers. I'm not sure of the blood alcohol maximums around the world, but I'd assume each car will have to be adjusted to certain rules and regulations.
