Unsealed. What a fascinating and more specific word I just learned today for what we call gravel roads.
That being said, you really have to watch that. There is a popular google maps cut-through near me that takes you down a road we call "bridge out" for, well, obvious reasons. At least once or twice a year the local tow truck operator has to figure out how to haul a car out of the creek down there.
There is another road that has been closed long enough that there is now a 30-40' oak tree in the middle of it, and yet google maps thinks it is an appropriate cut through between highways.
You really have to watch that in the country. The data is not great sometimes.
Oh right, i was adjusting my language for an international audience. We call them dirt roads mostly here, I think on account of them being mostly dirt, though they often do contain gravel. Up north some of the dirt roads are so thick with dust you need to leave a few minutes between car / road train so the dust settles enough to see.
But yeah, I have been sent on 'roads' that are just a little more than overgrown goat tracks, or across private land.
TBH I would try a lot of these roads even if I didn't use google.
Don't get me wrong, I love this feature but I can understand others would not.
