The satellite images also differ a lot from region to region. In dry regions, there are usually few trees, and you can easily see how wide a road is. But in regions with lots of trees, the treetops often obscure part of the road. So you might think from aerial imagery that it's only a walking path, but in reality, there's a full-width road beneath the treetops.
So it's hard to make a difference, but you can estimate some things from guessing what should be reachable by car.
