Mobile-app-based transportation company, Uber has some new technology that may just save lives. They’ve created an automated breathalyzer test that will call a ride for you if you’ve had one too many drinks.

Unsuspecting Canadian’s who were leaving their favorite bars wrapped up a night of partying to discover another alternative way to getting home safer. The idea was genius, and many people tested it out and put their keys away and let someone sober do the driving. Watch the quick video above to see how they reacted to a safer side home.

Remember folks, don’t drink and drive.
