http://www.telegraph.co.uk/motoring/news/6018081/One-in-three-road-accidents-happen-a-mile-from-home-survey-says.html As regards pedestrians being safer in 20mph zones, I noticed that whilst driving in 20mph zones I am distracted whilst poodling along, and will look around more often, and take less notice of the road. I have lived around here for 35 years and there are many things I have noticed that I have never noticed before. But on the plus side, if someone runs out in front of me and I hit them they will be less injured. And if someone is doing 35-40 mph and hits someone or something they will be easily convicted- no grey areas there.
