I just caught a bit of 'Clean Air for Kids' on R4 about School Streets in Hackney. Had not heard about it. (Must listen to whole programme properly in a bit!)
Seems like the sort of thing we should all be thinking about? I appreciate actually getting car-loving parents on board might be difficult, and there are probably a lot of issues that would need ironing out, but worth a try?
