We periodically have the same problem where we live. I hate the junk. My brother lost a good pair of running shoes thanks to a rock penetrating thru his sole. What really bugs me is because we don't get really hot here, it takes months of tires rolling over the stuff for it to pack down and become smooth, which means it never happens on the shoulders and bike lanes. Window dings, car dings, bicycle "gooed." YUCH!
