Trefnydd, I'd like a written statement, please, on the provision of 20 mph zones in semi-rural areas, as well as ensuring that drivers adhere to that speed limit. Recently, I've met with representatives and residents of Gwaelod-y-garth in north-west Cardiff, and they are fighting for greater safety for pedestrians, particularly older people and children, who have to walk through the village to catch the bus to the secondary school. There is no pavement in many parts of the village, and, for obvious reasons, they want a 20 mph zone through the village in order to make it safer. But, as you know, Trefnydd, it's one thing to get that speed limit in place; it's another to ensure that as many people as possible adhere to the speed limit, and that's a cause of concern in areas where there are these 20 mph zones in north-west Cardiff, in Creigiau. So, can we have a written statement on these issues, please?
