I spotted a thread at the Google Maps Help forum asking why Google doesn't allow people to walk across the George Washington Bridge. Specifically, why doesn't Google let people plot the directions as walking directions when traveling across the bridge. Any New Yorker knows, the bridge is filled with people walking or biking back and forth. It is a good question.
But when I was scoping out the bridge on Google Maps, using street views, I noticed that you can only get street views at the lip of the bridge. Any blue area shows where the street views are available, the plain yellow, is not available:
That reminded me that there is a law where you cannot take pictures of anything on the bridge. In fact, one day, I took a picture of the no taking pictures sign on the George Washington Bridge. I guess Google listens to those rules.
So why can't we get walking directions on the bridge? And why no directions to the moon?
