Indeed, by building a car-dependent society we've effectively disenfranchised those who can't participate. I remember some years ago, my wife was working in New Jersey and I flew over to visit here. There was a train from NYC to nearby and it looked like an easy stroll to get there (and I take a curious enjoyment from being the only pedestrian in American suburbia). Of course, her hotel was situated with no pedestrian access, but I noticed a path down an embankment, through some trees and then a neat cut-through chainlink fence around the hotel property. Evidently, that was how car-less hotel workers got to their place of work, which is sad if you think about that. It would have been a minor task to add access, but simply I suppose no one had thought about it. Those that didn't have a car had been elided, their choices curtailed.
