Did you like the article regarding risk?
On my phone i can't tell if it's a published article or just a blog? Who wrote it, what are their credentials, how did they gather the information presented? How did they come to the 25k per hour figure? I can't see any references either? (possibly because I'm on a phone though) Ahh too many questions...

Yes it's a Blog article. It's written by a cyclist who works at the giCentre a place where they know about data/statistics and how to convey them. Read the article on a computer, a phone is useless.
The thing about Forums like this is they are populated by a large number of very diverse people hiding behind avatars and the like. Some of these characters work in fields that are relevant to certain aspects of debate. For example, many here work in engineering, from mechanic to a rocket scientist. We have experts in transport, there are a lot of scientists, we have many experts in data analysis. We have medical experts, we have very senior and respected people in risk appraisal and management etc. etc. Without knowing this, many may look like pedantic, nay childish keyboard nobbers, who are actually smart and expert people using their substantial expertise to dispel common myth and supposition .... generally with great patience. Just because something appears obvious, doesn't make it true. Good data and analysis is the way forward.
The giCentre is based in the Department of Computer Science at City University London. We specialise in developing and applying new techniques for visualizing data. This ranges from visualization of 'big data' to personalised data presentation; from visual analytics to visual story telling; from cartography and GIS to statistical graphics.
We are a team of 14 academics and researchers with expertise in information visualization, cartography, design, computer graphics, human-computer interaction and geographic information science. As well as innovating in information and analytic visualization, we work extensively with a range of applied practitioners. Some of the clients we have worked with include Transport for London, Nokia, eonenergy, MediaCom, Unruly Media, Willis Group, Leicestershire County Council, the Defence Science and Technology Laboratory and the BBC.
That's all i needed to know, thanks.

But you don't care about statistics!
(And not all blogs are created equal...many academics now use them to disseminate their research findings in advance of publication)
More importantly, did Adrian deploy a thumbs-up winking smiley???!!**???***!!? Just when you think it's the same old sh*t till the end of time, you have to abandon everything you thought you knew and start over.
Nice attempt to avoid the question, but it still works for me.
Now I know that you will waste everyone's time by avoiding again, but lets at least try to get a simple answer form you.
Why do you feel a Thudguard is adequate in this case when you could have the additional protection of a proper motorcycle helmet?
Actually there was a discussion, but you were not really part of it as you kept avoiding answering the questions.
Cycling is not high risk, but I do not accept the extrapolation from population level data to me as an individual as valid:
As a pedestrian, I am to a large degree in control of the major hazards I face (ie when, where and how I interact with traffic by crossing the road). It is, by and large, careless pedestrians who come a cropper. I am not a careless pedestrian.
As a cyclist (as is SO often made plain in multiple treads every day on this and every other cycling forum) the major hazards I face are imposed on me by the vehicles I am sharing road space with. Even the most skilled and attentive cyclist is at risk from careless, aggressive or inattentive drivers.
(Almost as an aside: The fact that the population level risks are broadly similar,would seem then to suggest that the vast majority of drivers are in fact careful and attentive with regard to vulnerable road users)

It would appear that I did you the mis-service of assuming you had some intelligence. Read what you wrote above. Can you spot the glaring mistake? Hint: air does not absorb energy in impact. It takes energy to bend metal. What is it that deforms plastically in a crumple zone?

Except there is some data missing. The single vehicle accident fatalities are very similar for both pedestrians and cyclists. We don't have the figures for standard deviation (which, given the stochastic nature of these events, is likely to be high - as demonstrated by the large year to year variations in pedestrian and cyclist fatalities in the UK figures). The best we can say is that the risks of both cycling and walking are very similar.
You fail to supply absolute numbers of pedestrians or cyclists, or distances travelled by each group. Therefore it is impossible to make any judgement about risk per kilometre or indeed any meaningful comparison between them.
