Obeying red lights even there is no cars

As long as the red light was on, there was no cars at all, but the family still obey the rule. Perhaps they think it is safer and it is right to obey these rules. Especially when there is a child, maybe parents just want to set a good example.

There is another person standing on the other side of the road - also waiting. So everybody is aware that somebody else is waiting too. There is a pigeon on the street - a hint that there is no car approaching. The people in the Eiscafé are quite relaxed - but look at the situation. There might be a relation between the people in the scene as everybody is aware of the other ones. Maybe everybody would pass the street if he or she would be alone - but the shere presence of other people is a social control. So the red traffic lights create a relation between the people involved in the situation. This can be observed for people not knowing each other (and are just involved in the scene) and people knowing each other (like the group with man/woman/boy in the foreground) as well.

Actually we can't see it here clearly because of the picture, but the people in front of the street weren't waiting to cross, it was just a group of people gathered there on the corner of the sidewalk. That is what also made us though, if this family are the only ones waiting, and there is no pressure, why do they wait at all? Is it because of their child? Would they wait if the child wasn't there? Are they trying to teach the child to obey the rules or are they protecting him because they believe a really danger could come even in such a calmly street?
