A hardware prototype for Pennzoil designed to keep teens safe and parents sane. Allowance takes data from an internet-connected monitor (plugged into the car’s OBD-II port) and sends it to a mobile application on the mom, dad, or guardian’s phone. There, the app converts unsafe driving habits – hard braking, speeding, arriving home past curfew – into deductions from the teen’s allowance. A teen's safe driving habits will trigger an increase in allowance and, if they maintain a safe driving record, Pennzoil will match the money raised and contribute cash to the driver's college fund.
