This is more a complaint about these so called "tactile pads" in general. When they fall apart, either from aging and weathering or being run over by a snowplow, those little nibs of plastic or rubber pose a contamination threat to nearby soils and streams. Perhaps there is a better material or design that would accomplish the same goal?
I mention this now, because they are talking about putting even more of these, on High Street.
