Cars Of The Future Can Tell If You’re Drunk
February 1, 2011 2:20 PM 
An alcohol-detection prototype that uses automatic sensors to instantly gauge a driver’s fitness to be on the road has the potential to save thousands of lives, but it might be as much as 10 years off before we see it in most cars. This thing completely prevents the vehicle from starting if a driver’s blood alcohol level is above the limit of .08. “The Driver Alcohol Detection Systems for Safety” would use sensors that measure blood alcohol content in one of two ways: either by analyzing a driver’s breath or through the skin, using sophisticated touch-based sensors placed strategically on steering wheels and door locks, for example. Both methods eliminate the need for drivers to take any extra steps, and those who are sober would not be delayed in getting on the road. Course, if you drive by the bar around 6am and your neighbor’s car is still in the parking lot, you’ll know exactly what happened.
