I feel your pain Phaeton.
I have on these hallowed pages myself previously described how I was waiting outside school and observed a woman reverse her car off the driveway in the adjacent cul-de-sac, drop the kids outside the school a whole 100 metres away, then drive back.
And cul-de-sac abuse annoys me too. Those are turning bays built into the end, not car parks.
Our village is a little over half a mile long, the school, pretty much bang in the middle, and the schools catchment radius does not even extend to the edge of the village, so it is impossible to live more than a 5 minute walk away. And yet most people drive their overweght offspring to the gate. Indeed, they often pull off their driveway was I walk by and are still circling like sharks looking for somewhere to park as I stroll up to the gates. The effort and expense required to be that lazy is just indescribable.
