What I feel very strong about is the subway problems. The bad organization in addition to terrible manners of the subway users results in a routine chaos. It has been happening for many years; everyday, thousands of people prefer this transport because they believe it's faster and more secure. But what I can conclude is that each year we are paying more for the service and the wagons are getting so overcrowded and hot that we just can enter in it! What really amazes me are users who contribute a lot to make it worse. Some people don't know how to respect anybody, and kick others to make entering in the car something possible. As if that wasn't enough the organizers of the company are making a lot of changes "to make the transport faster" which only complicates it more.
