6. MotoSafety
MotoSafety is a teen GPS tracking device that connects to the OBD port (the onboard diagnostics port found on most cars built after 1996). The device rates and scores driving activity, and emails you a daily report card that summarizes unsafe activity like speeding, heavy braking, and rapid acceleration. It can also report vehicle use outside of authorized hours or areas, device tampering, GPS signal loss, and excessive idling.
