@herrchin: looks fine to me, except, would you be OK with the phrase below instead of "dense"?
proposal wrote:The Dirt Road / 4X4 Trail type has the unique property that Waze users may ask not to be routed over it. Users may ask to avoid it for all through routing with the settings option "Dirt roads - Don't allow", or to avoid it for through routing longer than 300 m (984 ft) with the option "Dirt roads - Avoid long ones".
Because of this property, this type typically represents side roads that some fraction of local drivers habitually avoid due to surface quality. In metropolitan or other urbanized regions, this generally means unpaved (dirt, gravel, crushed rock) roads, or roads in uncommonly poor condition by local standards. In other areas, roads with unpaved surfaces may be essential routes and thus necessarily set to other types such as "Street", "Primary Street", or even higher, as if they were paved.
Check your state page for details on whether your state follows unique guidelines for dirt roads, or contact your regional coordinator for further guidance.
