Numerous state legislatures have supported this objection with statutes prohibiting commingling. School administrators also found it difficult to schedule buses for midday and evening uses, a problem that persists today. Public transit authorities face the same kind of problems in conveniently routing buses for schools. In addition, school buses, then and now, often cannot accommodate some of the non-student groups most likely to need transportation. The elderly, for example, find the steps too high.
Most adults find school bus seats too narrow.
People with disabilities often require buses with lifts, features available on limited numbers of school buses. Lack of air-conditioning on school buses also poses problems for certain groups. On the mass transit side, public buses do not offer many of the safety features developed for school buses over the years. The seats are not padded as well. No stop signs, warning signs, and other traffic control devices are used on public transit vehicles.
