Have you ever thought about how school buses are routed? Every school day, every bus has to pick up some number of children, and then drop them off at a school on time. Ideally, the correct school. Some children have to walk to meet the bus, which must be taken into consideration because you don't want a young child walking close to dangerous areas, and then there are disabled children who need special buses. Deciding who walks, who gets to take a bus, and who in is some special circumstance is a logistical-legal interface which gets quite involved.

Making that all happen isn't just one job, it's multiple, especially taking into account the fact there's software to help which must be made, tested, and deployed, and which users must be trained on.

My point is, to the average person, adult or child, that whole little world collapses down to "school bus driver" and that's it. The companies which make the software I mentioned advertise, sure, but not to individuals, and school districts have no reason to advertise how, precisely, the sausage gets made, so this little world stays mostly hidden, unless the district offers parents branded software so they can track their children to and from school.
