Walking directions are a new feature for Google, and while I'm pretty excited about it, there are some rough edges that compel us to release it in "beta." Walking directions work well for short trips in urban areas, but we don't always know if a street has a sidewalk, or if there's actually a special pedestrian bridge for crossing a busy street. There are still a lot of pedestrian pathways we don't know about, and they might save you some time if you find them. We're working on collecting new data on pedestrian pathways and on more effective ways to solicit your feedback, so that we can steadily improve this feature and get you where you need to be as efficiently as possible. Walking is a great way to learn about a place, to get around, and to get some exercise when the weather is nice. You'll notice shops, parks, and public art that you've been accustomed to zooming past, and come away feeling like you've really gotten the insider's take on a neighborhood or city. Of course, don't get too caught up in enjoying the sights! Please be careful, and be particularly attentive in high traffic areas. Just like if you were driving, follow road signs and signals along your route, and use good judgment about streets that can't be walked (there are many useful websites containing safety tips for pedestrians).

Now if you'll excuse me, I think I'll get out of the office for twenty minutes and take a stroll.
