I've thought about this: if all transport is public transport, then how much is our physical freedom limited? Yes, bikes and other things may exist, but if all high-powered transport is outside of our control, how much control do we have over our movements? That being said, I think a lot of people in the US purchase cars through auto loans, and those loans while not physically limiting one's day-to-day mobility, can restrict one's job mobility. Maybe it only applies to certain economic classes, yet I imagine some people may be afraid to leave their job or lose their job because if they do, they lose their car and therefore lose their ability to move. And the safety net for physical movement in some places if one doesn't have a car is close to zero.
