LostExhaust takes advantage of the fact that everyone is going to and from the same place. By connecting people with those who live near them and drive a similar route everyday, carpooling becomes a simple way to save time and fuel while helping the environment by reducing carbon emissions. While other technologies either make users input a specific circle of friends or introduce users to strangers, LostExhaust uses trusted communities such as schools or businesses to expand sustainable carpools without compromising the information and safety of users. LostExhaust won the 2015 $10,000 Lexus EcoChallenge prize.
