they've indexed about 500.000 images now, so there is a long way to go - but they are still working. I haven't tried with any maps myself, but I could imagine that what you say is true for most, until they get further with their indexing. But at least they are "setting a trend" for image recognition so we get more of that... they are also beginning to collaborate with for instance Adobe.. so in 20-30 years... we got them pirates by the throat *lol*
