This seems to not take into account the size of towns. For example, the one I live in is ~23.5 sq miles. If you put the schools in the center, you're looking at approximately a 2.5 mile walk each way for the children on the outskirts (the town isn't perfectly round, but close enough). And even that is assuming there's a direct "as the crow flies" path; which there certainly isn't.

At the very least, for most towns, you're looking at moving a bunch of roads around. For many of them, you'd need to add more schools to keep the distances reasonable. I expect, for a large number of the town, the term "complete redesign" is a reasonable description.

Hm, 2.5 miles are 4 kilometers - perfectly walk- and bikeable. Any teenager easily can do that, over here, they would. I do not see the issue, especially since it will not hit everyone.

Alternatively, and this may be a radical idea: If your town is five kilometers across, with a uniform distribution of population: Why not have two, or three smaller schools, evenly distributed? A similar-sized German city (taking Öhringen, ~25.000 citizens, which also follows the 'almost a circle' rule, as an example here) has six highschools (which also take in students from neighboring villages)...

Money. A lot of it would be required.

I'd argue: money well spend. Also, smaller schools usually perform better when it comes to student success.
