First let me say that I would have no problem with my children walking a few blocks to catch a bus at a designated bus stop. I agree with all the points you have made. Will it happen here? Don't count on it.
I have more than one family member involved in school bus transportation in more than one district and at all levels (from bus driver to supervisor) and let me just say that most of the parents in WNY are NUTS!! I can't tell you the number of stories I've heard about parents who call furious that their child can't be picked up at their door because they live in a cul de sac that a bus cannot turn around in so their little darlings have to walk to the end of the block.
These are the same kids who will get into a fist fight on the bus and then be given in school suspension. The bus driver is then expected to pick up the same child and take him/her to school to serve their punishment. The same kids who calls from his/her cell phone and complain to their parents that the bus driver is mean. That driver then must be transferred off that route because the child couldn't possibly be wrong. And you think their parents would actually make them walk!
