It would be helpful to cover "when to report" also, or to suggest best reporting practices, in order to minimize misleading, superfluous, or otherwise inappropriate reports.
- Don't report moving police
- Don't report rain, fog, etc when it's obvious and/or occurring uniformly throughout the region
- Use the voice commands to make more specific reports when possible (with a link to the existing voice commands reference)
Setting best practices is essential in order to identify and correct misuse of this feature.
