Well, just a small post, to help a brilliant idea !
There is community that would love to see a new feature in the Google Maps project, that would help bicycle riders !!
They give all needed information here : http://googlemapsbikethere.org/
It consists of a new feature that will plot out a bicycle route on Google maps instead of a normal driving route. Also they would like to have a colouring scheme that indicates how bike safe the suggested road is.
All I can say is, sign that petition and push Google to implement this 🙂
