Here is a level of detail similar to a county by county view of the US.
Country 1
Country 2
At this level of detail one should be able to make out that these weren't pictures of countries but pictures of cars.
Until this level of detail is reached it is easy to be misled.
At this level of detail if one knows their cars they can identify the cars.
Although one might still be a weak fake and it'd be hard to tell.
