Runner here, I only communicate with cyclists by means of rude hand gestures because cyclists think they own the road and leave no room for pedestrians. At the stop sign near my house, not one cyclist slows down or stops and infact many have yelled at me when I am running across. V2V probably wont solve this problem but I wish cyclists start to yield to pedestrians and stay a safe distance away from us runners because we dont want to get hit by cyclist folks.
