Anything that can be seen from a satellite is quite accurate, that's true, but oftentimes things like number of lanes, type or direction of the roads is unknown

Anything that can be seen from a satellite is quite accurate, that's true, but oftentimes things like number of lanes, type or direction of the roads is unknown, footpaths in rural areas are very spotty. Basically anything that requires local human verification (addresses, business location, etc) is off limits and accuracy in those points comes from pre-ban times (or illegal activity).
