At Mini D's primary school 99% of children are driven there, despite the catchment being the 400 metre radius that encompasses the village. I mean, a 5 minute walk there and another 5 minutes back really is too onerous for most parents.
Anyway, the head teacher (and all credit to her) has become so concerned that after morning assembly any kids that were driven to school have to walk the "Daily Mile", 4 laps of the all weather running track. It's voluntary for children that walk to school, although most still do the walk, but they get the luxury of staying inside if it's chucking it down while the chauffeur driven sprogs still have to do it in the dire weather too
After the initial whining from overweight, self entitled, car driving, laze-bot parents, things have settled down. Attendance, academic performance and behaviour have all markedly improved.
