Adding security would further push people away from public transportation because it sends the message that the system/area isn't safe. And good luck trying to pry Americans (By far the most individualistic people on Earth) out of their vehicles, especially where our entire lifestyles revolve around them.I live in a community with bad mass transportation, and it has really affected my life in a negative way. It is hard for me to get around as there is only so far that I can walk (and I can walk pretty far). All we need to do is to enhance security, not eliminate a necessary means of transportation for people who either can't afford cars or who have disabilities that should prevent them from driving (do you really want a blind person to drive a car?). Having a car culture is a bad thing and we need good 21st entury mass transportation that is effective, clean, and safe to get people out of their cars.
