text: Secondly, one other advantage of car reduction is because it is becoming less nessasary to own a car.  For example, as stated in source 4, by Elisabeth Rosenthal, New York, is starting several programs to use cars less, including car-sharing, skyrocket bridge, tunnel tolls, and bike sharing programs.  In that source, it also says that when someone stops using a car, for whatever reason, they find it unnesasary to continue using cars, mostly because some citys are becoming more centralized again, and it's becoming easier to walk to stores.  However, thats not the only reason that it's being less nessasary to own a car. Another reason is because of improved telecommuting methods.  In source 4, Mimi sheller is quoted while talking about how people don't feel the need to drive to see their friend, instead they use their phone or computer to communicate.  Another reason for limiting car usage is because it is becoming less popular.
