Uber, the app that connects riders with drivers, has developed a curb-side breathalyzer to help keep streets safe. The custom-built kiosk helps guide users to hail a driver for a safe ride home, simply by blowing into it. The Uber Safe Breathalyzer is outfitted with disposable straws, a tablet and the Uber app, and a breathalyzer that analyzes the alcohol content in their breath after blowing continuously for 6 seconds. Everyone who participated and blew into the kiosk received a free Uber ride home for being a good sport.
This pilot program was so successful that it got pushed out worldwide from London to Singapore.
