Google Maps tests a new feature: walking directions. You can already get driving directions and, for a small number of locations, Google Maps has transit directions, but these directions are not always useful if you don't use a car or a bus.
Google suggests to "use caution when walking in unfamiliar areas", since the "walking directions are in beta". Chris, who sent this tip, spotted the feature for New York, but it's likely that Google randomly selected a small number of users to try the new feature and send feedback.
{ Thank you, Chris. }
