What IS the point of this money wasting exercise?
Surely mums (as mums it practically always is!) who drive their DCs to school, by and large either do it because:
-they work and unless they have a very understanding employer who will accommodate them being late for a week, may lose their job over this; or
-mums whom wild horses wouldn't induce to walk, let alone a poxy sticker scheme!
Once again it's attempting societal engineering via schooling rather than attack the 'core' of the problem- if, indeed it IS a problem- being the fact none of us have any time any more and many of us have mortgages or rent to pay! Furthermore, really, why expect DCs to trog to school in all weathers when we, as adults, take the car everywhere?
I wish schools would spend the money on sticking to the point and schooling our DCs not rewarding behaviour 'walkers' already do and guilt tripping those who can't!
