Waze should show all roads with the "Unpaved" attribute as brown, the same way the "Off-road / Not maintained" are shown.

It should not matter what the type of road is. If it is unpaved, it should be shown to the user.

This is especially a problem on private unpaved roads, where you cant even just go in to the WME and change the road type to "Off-road / Not maintained", as that would mess with the routing. Knowing the state of the road you are about to drive down should be an important thing, and is why people even use waze in the first place.
