While I understand this intellectually (that is, I know that this is an American-centric thing, and that other societies in the world have a different view), I am curious how this view would be justified?
One could "reducto-ad-absurdum" the statement, and say "To be bedridden and unable to walk is to be free!" - which would obviously be a very absurd statement to make.
In America, part of the reason we feel this way is because of our vast travel distances compared to other areas of the world; it isn't unknown for people to commute to work over 50 miles (80 km) one way. Or to travel that far to go shopping.
Travelling to another state could easily be hundreds of miles and hours of travel. It would comparable to driving between countries in Europe (assuming a similar "interstate" freeway system).
We want that freedom so that we can live where we want to live, shop where we want to shop, play where we want to play, and work where we want to work - and not have that dictated to us based on economic situation, geographic location, etc. If we want to live in the slums, and commute to the "rich part of town" to work (or vice-versa!) - even if the distance is fairly large - we want that kind of choice.
One could argue about other forms of transportation - but those come with costs, and in the US we don't have great public transportation - and ultimately, you are chained to the decisions and whims of the transportation and other people using it; you can't decide where and when to go, and when to stop, or when to be picked up...
So I guess I'm trying to understand the statement "it is freedom not to have a car"? How is it freedom not to have faster, longer distance personal transport? I can understand economic freedom (it's expensive to own a car - and even more so if you have to pay to store or park it), and I can understand the licensing argument - but in general, being limited to the alternative options seems to me to be less freedom, not more.
I'm obviously missing something...
/also - I like to go off-road - 4-wheelin' in the dirt and mud - can't do that without a vehicle (and currently, you can't do it with anything not IC powered that is available to consumers at a decent price - and I don't know if an autonomous ORV would be fun or not - but I can't wait for 4wd electrics that can be lifted and modded with big 44" mudders).
