"Driven By Efficiency" is a mobile application that encourages users to drive less aggressively and more fuel-efficiently by using real time data and social pressure. More specifically, the application calculates and displays the "hidden" cost of gas per gallon based on real-time accelerometer data. Driver defensiveness is also calculated based on a scale from 0% - 100%, automatically posting this information to the user's Twitter account after each driving session (i.e. "John Smith is currently driving worse than 70% of drivers on the road.")
