Consider the school bus. Busy in the morning and the afternoon, school buses sit in between and at night. What if we got them out on the streets, picking up passengers and dropping them off at intersections, all over town? New York City, the NYTimes reports, is moving to use school buses to help elderly citizens get to grocery stores and the like. Much, much more could be done with school buses. In many countries, buses do double duty, carrying students to school as well as providing transportation to citizens.  It’s time to get them on the road.  We’re paying for them, after all.
