It disturbs me that your comment is "greyed out," whatever that means: you're speaking an obvious truth. The car-scale of American infrastructure is an impediment to physical health; it's an impediment to social capital, and therefore to democracy and to mental health, as well. It funnels us down restricted, commercial avenues--pun intended. It's physically dangerous, it's chemically toxic, it's ecologically destructive, and it's damned expensive to maintain!
It's obvious when I visit a city / countryside with poor transit and pedestrian infrastructure how much more I suffer. It's so damned obvious, it's the first thing that screams out to me right when I land / pull in / ride up.
I can't understand what literate person would take issue with the core of your assertions.
