This is cool… my friend Mike Mathieu set up a web page where you can enter an address and find out how walkable it is.
Microsoft’s campus gets a 31 (“For most errands, driving or public transportation is a must.”).
The Googleplex: 34. Good thing Google gives you a few bucks towards a Prius.
The Fog Creek office: 98 out of 100. (“Most errands can be accomplished on foot and many people get by without owning a car.”)
Conclusion: Ditch your car, work at Fog Creek.
