Like sheep over a cliff, two cars followed the leader.
Now bear in mind that no driver in this situation can see a red or green traffic light. Yet sit they do until either someone tells them or they take action against the lights, or just make a U turn, which is what the two cars behind the leader did. Still the driver sits as the traffic lights cycle through. It was early morning and there was little traffic going the other way. Now here comes a Mini after the other two cars turned back.
Finally the car turned left into St Kilda Road and the Mini made a U turn. Often these are cars coming out of side streets, but in these instances they weren't. They just drove down the wrong side of the road. While I think they are stupid, when so many people are stupid, maybe there is signage or road guidance problem.
