Wow, a late run bus is such a great idea! DS/DD literally have no time to stop by their lockers on the days that they take the bus home.
Along the same vein, the system really discriminates against kids who do not have access to private transportation or live within walking distance of their school. Our district recently adopted a new philosophy of grading, which aims to encourage learning and emphasize ultimate mastery by allowing students to "re-do" smaller assignments and quizzes to earn a higher grade. Unfortunately, that meant kids have to either come in early or stay late on the date/time scheduled by the teacher. I am just thankful that it is extremely rare for DS/DD to redo any assignments/quizzes.
