A Philadelphia councilman wants the city to look into installing rubber sidewalks. He says they won’t crack, will last longer than concrete, and would reduce the number of slip-and-fall accidents and the lawsuits that result from them. If the city goes for this idea they should look into an idea I had many years ago: rubber streets and concrete tires. The streets would expand and contract with the weather, eliminating potholes, constant repair work, and wear and tear on cars. Tires would last longer because they couldn’t go flat. And should you actually get a chipped tire, you’d simply whip out some spackling and the next morning you’re good to go. Next problem!
