You can combine bus routes so if a family has twins a boy and a girl (Or more likely children a year apart), but they go to seperate schools, the school bus can pick them both up and drop each off at their respective schools, this is more efficient and money saving.
Not happening, and you know it. Even if it was offered, private school parents in Lakewood Ir HaKodesh would not send their children on such buses.
More likely to save money (from what I read) is the removal of Helen Tobia, and the monitor banning any outside placement for special education services, especially if the parents are represented by Michael Inzelbuch (whom the district should ban from any cases due to conflict of interest). Something like a moratorium on any placements until they can settle things and do some forensic accounting on the schools who accepted outside placements to see if any illegality occurred.
I imagine that will save a signifigant amount of money for the district. :p
End story, the district will run out of money and the state will not offer any.
