We live in very different areas. There might be 5 families that live within a mile of our school. But even if they did, there aren't sidewalks or even shoulders of the road for them to walk on or ride a bike. I'd be willing to bet there isn't a single kid that walks to our school. Looking at the school pick up, the rare times I can pick my kids up, I'd guess than less than 20% of our district are brought to or picked up by parents. More than 85% of the kids in our district live on gravel roads. Our school has less than 800 students k-12 and the district covers almost 200 sq miles. So like a tiny % of kids even live within 2-3 miles of the school. My kids are on the bus for an hour on the afternoon. I can see cows from the bleachers at the football field lol. Heck our entire county is almost 850 sq miles, and the last census, the population was less than 50K people. So we can't really compare the 2 situations in any way since it sounds like where you live, parents don't have a choice but to take their young kids to school.
Here, your kids can only go to the school district in which you live unless you send them to a private school. And where we are, that would be a 45 min drive each way, 2x a day.
I will say, since COVID I know more families have 1 parent at least who WFH, which would make it easier to pick up or drop off.
