Cycle campaigning

I close the topic where I found the link by mistake but this one is exactly what I'm talking about;

The threat of a daytime lorry ban, almost universally dismissed as unworkable, might serve to concentrate minds, given that it would carry considerably greater costs, especially in the construction sector. I realise that there is currently a night-time ban on lorries in London, but this should be done away with. This ban dates back to 1982, and I have no idea at all why it was brought in. We want as many HGV movements at night as possible, surely?
