	As any city dweller realizes, cities can be extraordinarily dangerous, for movement there is an uncertain as that on a battlefield. The pedestrain must move around automobiles, trucks and other innumerable obstacles with the quickness of a rabbit and the muscles of a weight lifter. In addition, he must also protect himself against the actions of his fellow citizens. For example, an innocent visitor unaccustomed to the actual violence occurring in subway travel, could easily suppose he had walked into a riot.
	Expressions of annoyance are quickly uttered, arguments are begun, blows and kicks are given and the frightened visitor is eventually pushed from the train to a station platform and not the one for which he had been heading. Much the same struggle continues at bus stops, and this confusion is often initiated by the dirver himself. Passengers who have sprinted widly to gain transportation and have actually touched the bus itself find it ia usual happening to have the door slam shut just as their grasping fingers reach in vain to keep it open.
	Some passengers, feeling their patience tried beyond normal endurance, actually follow the bus, screaming insults and holding aloft clenched hands. At other times, passengers, feeling exhaustion and misery at the finish of a difficult working day, are further annoyed. They have to mark time in snow or rain while waiting for a bus as one half-filled vehicle after another zooms by. Admittedly, problems between passengers and driver are not always the driver's fault, and occasionally those unfortunates driving have reason to bemoan their profession.
	Sometimes passengers, especially visitors, dealy scheduled by demanding information or asking question that could be easily resolved by reading the directions on the bus itself. Often they become troblesome, refusing to move to permit others to come in. The people belonging to a particular community or to a particular caste and by helping the families of those persons who were thus engaged in educational pursuites during the period that they were so engaged.
