It would be useful for Waze to default to safest routes (ie, least prone to flooding based on historical data which I am sure exists) in case of such weather events (even just suggest it in case it has been raining heavily in the last few days in a given area). The report flood button is not enough - how do I know the alternative itinerary I choose will be better or if no one has yet reported a flood?
It is becoming increasingly necessary given the climate events the world faces.
