If a Waze user turns off unpaved roads and goes somewhere requiring their use, they should receive a pop-up warning before starting the route instead of taking them as close as possible. Something like: “All routes to [ADDRESS] require driving on unpaved roads. Would you like to continue?” The user should be able to temporarily opt out of avoiding unpaved roads.

Oftentimes, a user who turns off unpaved roads is routed far from the actual destination.

I edit in a U.S. state with over 50% unpaved roads. This addition would improve the user experience significantly, especially since the state relies heavily on tourism.
