Google has added bike paths to its Google Maps service. You can now plan your trip to take bike paths into account. They are separated into off-street, on-street and “bike friendly streets”.
Some quick browsing through it reveals that it is still a work in progress, with some bike paths missing or inconsistent (i.e. in some places a shared pedestrian/bike path is classified as off-street and sometimes as on-street). Still, this is a big improvement, along with the addition of traffic that was added recently.
What Google Maps is still missing in Australia is good Google Transit functionality. It’s almost non-existent in Australia, with Sydney having only the light rail and monorail built in. Sydneysiders can use something like 131500 or the TripView app to get directions, but I found neither of them to be as user friendly as Google Transit was when I used it while travelling in the US.
