I have a knack for finding good driving roads with Google Maps.
It doesn’t really work in satellite view because the trees make for a ton of visual noise at the relatively low resolutions shown.
A good indicator for me is green in the map, and no street view (street view tends to cover busier routes, I drive roads street view wouldn’t bother with)
That's an interesting point, as all maps are (by definition) only representations, invariably leaving something out - the question is what to leave in the map.
Would you even trust an "interpreted" map with levels of green for what you're doing?
