Only by traveling to places that were developed before cars took a chokehold on the world can people realize how nice it is to live without them absolutely everywhere.
Many Americans get a taste of that when they vacation to Europe. They often choose to leave their suburb and spend their 2 weeks in urban environments like Barcelona, London, Munich, Paris, Rome, etc., that where built for people and not cars, because it's so pleasant to live like that, and because letting cities develop for people first leads to cities that people actually want to be in, with car-free streets, plazas, promenades, etc. (Yes, today those places are also full of cars. But, unlike American cities, their skeletons are people-first and cars are the invasive element.)
It could be argued that so many problems of American life - weight gain, loneliness, fracturing of the social fabric - stem from how we've isolated ourselves in unwalkable suburbs, where there's no spontaneous social interaction because everyone's always in a car, and where our only exercise is the walk from the parking lot to our desk.
What's depressing is visiting developing countries and seeing them start to ape the worst of American car life. Places like Colombia, which I visit often, are building shopping malls, big-box stores, parking lots, suburbs, and freeways, while after almost 100 years of that type of car-first development in America we're only just starting to realize that actually it might not be that great.
I can visualize it just fine... High Density, people stacked onto of each other vertically, small dwellings where you need to shop for food every day or every few days, extreme cold or extreme heat is a problem, as is rain...
Instead i look out to my 3/4 acre homestead, lined with mature tree's and limited density... and say... yes I prefer this. I prefer going to to store every 1 or 2 weeks, I prefer not having an upstairs neighbor stomping around, I prefer not having to deal with stairs or neighbors only separated by a wall...
The same way it is unreasonable to think that less car centric cities would solve all our issues, it's just silly to equate "non car-centric environment" to "dystopian cities where people die on the street whenever there is a bit of cold".
I dont shop at the closest store to my home because I prefer the layout and selection of one that is further away, i know people that take their kids to schools across town because they are better than the one closest to me. (in my area schools are not assigned geographically, we have open enrollment at all public schools)
Cars give you that option, with out it you have THE store, and THE school... sorry but count me out of that
