People don't ride the subway to watch the scenery. They are trying to get somewhere. We'd find it odd if someone got onto the subway to ride somewhere but never got off the car but instead just rode back to their original location.
I suppose, though, that we do this with our beliefs and attitudes. We have a particular way of being that we depart from when we're angry or our blood sugar is low or we're in a panic about something but then we drift back to who we are, largely unchanged and still ourselves. We consider new perspectives but return to our own. It seems very difficult to actually get off the train and move to a new location.
