I guess I can understand your second point, but from your first point I would draw the conclusion that right now it's not safe, then, to seat three kids to a seat. By saying that now you need 100 more buses to essentially make it safe.... As a dad of two little girls who take a school bus—not in your jurisdiction, but back home—that would worry me at the end of the day, that buses aren't safe the way they currently are.
I'll give you a chance to comment. Again, I'm speaking from the perspective of a parent who has kids in the school system.
