Google just announced extended availability of biking data and directions throughout Europa and Australia:
To use biking directions, select the cyclist icon from the list of routing modes when you search for directions. Watch this short video for more information. Biking directions are now available in Austria, Australia, Belgium, Denmark, Finland, Netherlands, Norway, Sweden, Switzerland and the United Kingdom.
Notably missing from this list: Germany. I wonder how Germans (and thus I) deserve being punished by the unavailability of directions for public transport and biking. At least on mobile these are very important features. Probably because we’re a „car nation“.
