LIVE Number plate scanner, last known position of police vehicles.
A button to enable the camera to scan and track known number plates of police vehicles (possibly other wazers).
This can have a refresh time of say 10 sec and shows the next known position or simulate the police vehicle movement on the map. It just disappears when it loses the tracking but notifies users of recent police presence if you enter a road that had police vehicle on it in the last minute or so or within a certain distance.

Sadly the technology is not there yet. Vehicles with this capability currently have large obtrusive cameras mounted to their trunks, and still do not work well at night. There's no possible way you;re going to make this work with a smartphone, unless you are OK with mounting your phone to the outside of your vehicle.
But a great idea! Especially to identify unmarked cars!
