Rubber sidewalks are the future. Concrete sidewalks bend and crack too often, even with expansion joints. So, why not make the entire sidewalk the expansion joint? There are tracks around the world made of rubber surfaces, it's gonna be better to walk on, better to run on, can respond to changes in temperature, earth movement, and roots of plants much better than concrete or asphalt.
