I grew up in a rural place but live in NYC now. It took me a while to get into the rhythm of having things nearby. My family from suburban and rural places always seem surprised when I mention I need to run out to the grocery store at 6pm on a Tuesday. For them that’s a once a week trip at most–I can probably get there and back in the time that it takes them to get to just get to the store.
I am not making a case for the superiority of one lifestyle over the other (though I see suburbia as kind of a worst of both worlds between urban and rural), just offering my interpretation of why people in America might feel this way.
