I had the opposite thing happen to me this last week. I was riding 20 in the bike lane and a woman decided to jay walk across the 4 lane busy road, looked both ways and then stepped into the bike lane in front of me and the decided to pause again to check for cars, but completley ignored me when I yelled "hello" and "watch out" and had to slam my breaks to slow down for her to cross in front of me. It was really dangerous and then it took me 5 minutes to get unticked that she didn't at least make some sign of being sorry or surprised she had almost gotten hit. She completley ignored me. arg.
