Rubber Sidewalks: Good and Green?

From HUGG: "Washington, DC, is experimenting with sidewalks made out of rubber. The benefits of this are two-fold. First, tree roots grow where they should - down. Second, the sidewalks are made from recycled tires, keeping them out of the landfills. The sidewalks last about three times as long as the concrete variety, reducing the need for constant maintenance. Everyone comes up a winner!"

Let's hope. I've used rubber sidewalks elsewhere and they also seem easier on the feet. But I have a hard time believing they're more durable than concrete. In any case, a great way to recycle and, if they really do discourage root disruption, keep landscaping healthy as well!
