I'm absolutely for certain roads being 20mph. Especially all the roads near pubs like The Castle, The Great Exhibition, The Actress etc. Those roads are narrow with lots of side roads and people should drive slow and take extra care. But I also think common sense should be used especially with big wide open roads like Sydenham Hill. Maybe a couple of speed humps before the bends or as mentioned earlier, islands for crossing. Or maybe more zebra crossings? I just worry because I see people getting frustrated and overtaking, creating dangerous situations. If they could stick to 30 they wouldn't do this.
