Review of MDR

SmartWheel Functionality? ● Monitor car acceleration. (accomplished)

● Send message to registered phone with coordinates when acceleration reaches certain level. (accomplished)

● The app could extract the coordinates from message and show it on map. (accomplished) ● A home-box could gather and sort the driving history. (CDR)

For whom the SmartWheel is designed? ● Parents

● Insurance companies
