Apparently Google is considering creating maps of the best bicycling routes in any particular area, because the idea has been posted on their ‘Suggest It’ page where the merits of possible new developments are weighed by the public.
If this seems like a good idea to you, go to the Google site and “vote” by clicking the ‘Suggest It’ button. The bike route mapping is under the heading ‘Route Information.’ If Google is flooded with requests, the proposed feature could become reality.
