In order for a public transit system to be adequate to transport children to school, it has to be adequate, full stop.
In the US, a separate public transit system specifically for schoolchildren exists, usually because there is no effective public transit system for everybody. A child cannot catch a city bus from their home to their school when no city bus ever comes within 3 miles of their home.
Europeans often don't understand, because American urban planning makes it seem like one would have to be a madman in order to do things that way. It's not madness. That's just the way the economic incentives aligned in the past, and no one has cared to re-break the bones in order to set them properly, so everyone is crippled from birth by the history of the infrastructure.
