As a result, streets with heavy traffic will be avoided whenever possible. Note that this mode enables traffic-aware routing.

Both RouteOptions.departureTime and RouteOptions.arrivalTime are ignored, and the route will be shaped disregarding all the available current and historical traffic information, except long-term road closures. Note that this mode disables traffic-aware routing regardless of other settings.
