Waze is a community sourced navigation system. Think GPS in your car. However this is not your “fathers” GPS. Waze is a Google owned company which allows it you use the strength of Google maps, the Google ecosystem of social accounts (your existing google account) to find friends and share traffic information together in real-time. While contentious it does offer the ability for commuters to tag events as they happen and alert other commuters such as traffic accidents, road issues and police stop locations!
