My town ditched almost all of the school buses and the kids ride public transit. I haven't lost one yet!
As a bonus, they learn that they can take these buses everywhere else and gain access to the entire city.
So how do you solve that problem? If kids use public transport there is more demand for it which means there is a justification for increasing provision which will make more people use it.
Kids on public transport is common in most of the world.
I thought the suggestion was to use them for something else during otherwise downtime.
