I grew up very poor; my family had no car. During the entirety of my childhood, we either walked to the store, or paid the local "taxi service" (in smaller places, it's not a traditional taxi, but someone who operates out of home/small office answering calls) $5 for a ride (it'd probably be $15-20 today, but the idea that you can't survive without a car is a bit silly, even in small towns)
