What would help the social contract succeed?

Social contract theory, nearly as old as philosophy itself, is the view that persons’ moral and/or political obligations are dependent upon a contract or agreement among them to form the society in which they live. Socrates uses something quite like a social contract argument to explain to Crito why he must remain in prison and accept the death penalty. However, social contract theory is rightly associated with modern moral and political theory and is given its first full exposition and defense by Thomas Hobbes.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
