It's an elementary school.
Lafayette, Louisiana is so car dependent that their brand new elementary school is built like an industrial center where trucks line up to deliver and pick up goods.
All of this for a demographic (kids) that can't even drive.
I mean that's disingenuous statement. It's Clearly built to emulate the drop off/pick ups of airports. Clearly you've never been to elementary schools in the morning and afternoon where there's lines of cars for parents dropping off their kids and numerous buses doing the same on the other side of the building.
It's clear no one is going to walk to this school. So the kids have to be dropped off by car or bus. To move traffic off of the main road and provide parents with as fast and as safe drop off/pick up as possible, there is a large 4 lane road to keep traffic moving.
This isn't egregious use of land and roads when it fits the actual demographic - parents who want to transport their kids themselves.
