Actually, there's a good idea in there...

From the BBC:

The charity* is calling for more action from central and local government - and parents - to get more young people walking.

In Hertfordshire, it says a pilot scheme it was involved with, funded by the Department for Transport, led to more children walking. Tactics included offering incentives, such as badges or stickers, to children who walked to school, plus promotional events.

A "park and stride" scheme was brought in, where parents dropped their children at a place close enough for them to walk to school with a teacher or other nominated adult.

* The "charity" is called Living Streets. You know straight away that this is probably a fakecharity story because it's full of crap about the "obesity epidemic" and the article ends up with a spokesman for the government agreeing that "more must be done", but let's just check... aha, right, just look at their list of sponsors, it's mainly government departments and other fakecharities.

But the "park and stride" could be a very good idea - in certain circumstances:

For example, I walk my little girl to school. It is next door to another school on a narrow one-way residential street, and there's another school on the other side of the main road (behind the two schools), and of course most of the mums drive to school and then they have to stop and chat and admire each others' 4x4s for ten minutes so the whole thing is a nightmare. Why is it that women always have to form groups right where it is most inconvenient for everybody else, for example in a doorway or clogging up the pavement outside the school? All the dads just drop off their children at school and then stride purposefully towards the Tube station.

These three schools could do the walking parents and local residents a huge favour by asking the parents who insist on driving their little pets to school to drop them off somewhere where parking is much more convenient/safer (there are a couple of large car parks within ten minutes' walk), and every five or ten minutes, a responsible adult could accompany a group of them up the hill and drop them off at their schools (the uniforms are a handy kind of colour coding so that it's easy to make sure the right children go to the right school).
