Why doesn't Greece have street view on Google Maps?

Only museum views for Greece have been added to date. Both the Monastery of Saint John the Theologian and the Acropolis Museum in Greece were added to google Street View through the google Art Project in 2012.

Street View is not yet available in all countries. Greece as listed is one that will be added in the future. The world is a big place and google is striving to cover the entire world, but it takes time. New countries are added as often as possible.

google usually has partners in the various countries that drive the cars around taking pictures then send results back into the google data center for processing.
