Unmarked police vechiles
I have an idea for a feature that could make Waze even more useful for drivers.
It would be great if users could report unmarked police vehicles in the app, similarly to how they currently report visible police. Users could optionally enter the vehicle's license plate number, make, model, or color (if known).
When another driver approaches the same area, Waze could display a notification such as:
"An unmarked police vehicle was reported here at 2:15 PM. Reported vehicle: black Volkswagen Passat."
This would give drivers more awareness of their surroundings while also showing when and where the vehicle was last seen. Since the vehicle may have moved, including the report time would help users judge how relevant the information is.
