All the motor cycles make their way to the front of the queue. When the lights change to green no one wishes to be the 1st to move as there's always a couple of red light runners - it becomes a game of 'Chicken'.
Any dog not on a lead with its owner should be treated thus. If you want action, cut/paste this story across FB et al. Bad publicity is the only way to get any action round here.
