Nissan has developed a cool new technology designed to stop drunk drivers from getting behind the wheel. The cool part is that it's not just about your breath. Yes, the technology includes odor sensors that analyze your respiratory exhaust, but it also measures the perspiration in your palms and checks your alertness levels by running an eye scan.
If the system thinks your drunk, the car won't start. The question, though, is how it's going to determine that level. There's no set schedule, but Nissan hopes to install the system in time to cut road fatalities in half by 2015.—Gregory Mone
