I'm not sure this is really a challenge with regards to fact, because you do cleary state that it is hypothesis.
At least it proves that this forum works. I'm sure some folk were beginning to wonder seeing as no posts have been made since the forum started in March 2004.

However, on the

- Motorbikes travel faster (unlikely).
This is not my experience of urban traffic. In my experience Motorbikes are able to travel significantly faster than other traffic, because the queues usually only slow us down.
The page does give official data and an official reference to motorbike speeds in free travelling conditions. Like you, I have my doubts that the official figure correctly describe motorbike speeds. I suspect that motorbikes are the fastest moving vehicle class in many 30mph zones. However this is not what official figures tell us.

However, I'd like to see official data seperated for learners and qualified motorcyclists. I have a hunch (and there is some data to back this up with age and engine sie distribution) that learners represents at least 50% of casualty data in urban areas.
However, pedestrains failing to anticipate a filtering motorcycle is in effect a kind of SMIDSY. The vast majority of people (drivers and peds) do not expect to find moving traffic in a stationery queue. I think this is likely to be the highest contribution to ped risk.
Yes. That's listed on the page and we rate it as "likely" also.

you may also want to consider the 'tangliness' of a rider/ped interface (and this applies to cycles too. With the exception of scooters bikes are not really ped friendly from a crash point of view.
The page contains: "In accidents, projections cause worse injuries. (likely)" which is a different way of making the same point I think.
