When driving, waze allarms me for cars on the road banks, speed trafic cameras policeman ahead hazards etc. Also I can see other wazers on the map.

With my windows closed, if there is an imergency syren yelling by, I often fail to locat the exect location and direction of that ambulance/ police or fire fighters. I think I am not the only one feelling so.
So.

If all the emergency units on the road wil be on the waze, it will prompt the souranding driversv for rheir existance and exact location on the users maps.
That will help us all to help them through.
