Putting these in Ann Arbor or Tuscon would be the best test. How does it fair in freeze/unfreeze daily cycling like in Michigan? Hows the rubber stuff work in Tuscon where you really can fry an egg on the sidewalk? What's the cost benefit to cash pinched cities, the maintenance, etc? What happens when bored teens try to drain it or inflate it with bottle-rockets? Does the goop damage paint? ETC. I feel this is a Silicon Valley 'Problem' where everyone else has much tougher/different ones than the Redwood City slogan of 'Climate Best By Government Test.'
