crossing road with crowd/group/herd is for economy
Dr Faria said the behavior could be because people feel safer when making a dangerous crossing with others.
the scientists, it seems, do not know, do not keep in mind, how much energy use/burn one automobile against how much energy uses one pedestrian. going “like herd” is just economy for the god would be pleased. i think. it is so in pedestrian crossings through automobile roads not regulated with traffic lights.
