It isn't one of the listed offences but what makes me craziest is when pedestrians travel in dawdling rows of 3 to 5 people, effectively blocking faster traffic behind them as well as all oncoming traffic. This seems to be particularly prevalent in my neighbourhood where everyone is out for a carefree stroll on the way to and from the many bars and restaurants. The worst are the droves of young women with more make-up than brains who form impassable human barricades as they move along the sidewalk at a snail's pace. Is this a pick-up technique? A big, slow-moving pack of ladies is more likely to catch the attention of the menfolk?
