I live in a small college town in New England. I bike our toddler to/from daycare, our first grader either rides her bike or walks (about 500m). They’ll be able to walk to school through ninth grade, at which point she can ride a bike or take the bus or hitch a ride with mom. It’s definitely possible in much of America, if you simply choose to do it.
