I mean, in a basic sense, if you choose to live so far away from your job that there only exists one possible transport mechanism, then yes, you are dependent on that one transport mechanism. If e.g. a city metro ramped prices then many people in outer zones would have the choice to either pay it, move job, or cycle/walk in. If they bought a house next to a station with no other good transport links and no local work, well, it's not as if that wasn't known...
