Saab has been working on a built-in breathalyzer for the last few years and now, it's going into real-world trial in Sweden. Basically, it works like a combined breathalyzer and anti-theft system. Saab expects insurance companies and governments to subsidize this feature and hopes customers will elect this as an option. It appears a little odd that Saab would invest in such a technology as the market for such a device is questionable, but I am glad to know that there's a company out there that cares so much about the occupants' safety. There are many questions as to its real effectiveness as a deterrent. I hope that Saab publishes a study on the alcohol-related crash rates between regular drivers and those who use this device. If they do, we'll cover it.
