Nah, I just keep my hands on my brakes, go slow, and expect peds to do just about anything. Just today I scared the crap out of a guy that was walking along the trail then decided to do a hard left. LOL. Bet he looks in the future! I just swerved and avoided him.
Yet another argument in favor of riding across crosswalks. If you don't take the time to jump the curb, unclip, dismount, push the button, move your bike out of the way, etc., the green light won't last long enough to make it across and you'll totally be car bait. This happened to me today also, but thankfully I was riding across!!
