Ther are 20 mph limits all over Nottingham city.
Complete waste of time as [almost] no one sticks to them.
As to pollution, and safety, a car doing 20mph will be in an area 50% longer than one doing 30mph, so even if the engine is putting out the same fumes in both cases, there will be 50% more pollution in that area (and I always understood that at lower sppeds, engines put out more pollution).
To actually stick to 20mph, you have to spend a lot more time actually watching your speed, so less time watching the road, I dont see how thats safer for anyone.
