Nah have not set any as dirt roads, and I have not added the actual rally stages so that Waze doesn't try and route us down them
Well, I actually have added the legendary Swamp Road, but I have set the junctions so it is non-routable. Will correct it next week so that it will be routable on the next map build.
Most of the areas of the rally, especially day 2, don't have phone coverage, so Waze won't be much use anyway.
