There's an entire section and even a chart in the article that explains why this is different now In 1969 only about 30% of kids lived too far away from school for walking to be a realistic option. In 2009 (and today) that numbers is around 80%. Walking to and from school is great if you can do it. Most people cannot do it.
why are schools farther away now? That's interesting.
It's also fashionable for parents to choose a school across town for arbitrary reasons in order to signal that they care more about their children (in my opinion). We have tried advocating for the local options and the positives it has had for getting to know others in the community but most don't even consider.
I'm lucky to live in an older neighborhood with an elementary school, middle school, grocery store, and a few other shops. There are also safe ways for kids to cross from adjacent neighborhoods so there is still a lot of autonomy for the kids getting to and from school.
