Is the smartphone app “Waze” a benefit?

I had never heard of this smartphone app “Waze” until I saw news article after news article pertaining to the controversy of whether or not this app is helpful or harmful to consumers and law enforcement.
You might ask what is Waze? It is a smartphone app used mainly for navigation. Waze remembers users’ commonly used routes and tells users what traffic events will be encountered on any route.
