Google This

We would like a 'Bike There' feature added to Google Maps - to go with the current 'Drive There' and 'Take Public Transit' options.

The feature would take into account actual bicycle lanes from the locality being mapped, and it would automatically plan a route for a bicyclist, possibly even providing the cyclist options for either the most direct route, or the most bicycle-friendly (safest) route. The Google Maps-based third party site, byCycle.org (http://byCycle.org/), provides these features for two metro areas - Portland, Oregon and Madison, Wisconsin, and there are countless other mapping initiatives around the world aimed at accomplishing the same goal. We hope that Google will consider building this feature into the core Google Maps service.
