Waze helping to avoid danger in Streets in the city
Waze could help better the society by allowing users to rate the quality of roads related to vehicle compatibility in order to avoid danger, as a bumpy road could be very dangerous for a truck that carries gas or any other HAZMAT, along the tracks with many holes.
Also, users could write down the places where there are people in danger or abandonment (drug addicts, alcoholics, victims of crime, homelessness, etc.).
This could be a more powerful tool that could help society by allowing users to know better the safer route to follow, and also to the government authorities to have data to be able to take action to avoid the dangers of explosions by burning trucks, assaults, help people in need, etc.

Waze is meant to be used by drivers of passenger vehicles only, so hazmat is non-applicable for Waze.
