I... use Google Maps a lot for day to day public transportation, in France. Most of the transport systems are integrated it works wherever I go, in Ile de France but also plenty of other cities, including smaller cities like e.g. Chartres. YMMV Went to Porto too recently, same experience. Very cool, especially as a first approach when you don't know the city enough to plan and orient, or if you are like me and spend hours wandering randomly deep in cities...
