Motorcycles in your bus lane

Do you know of locations where moto's share with cycles?
What's the collision rate between the two road users like?

Surely you'd need a trial run arranged on a bus lane somewhere (like the one way test for cycles on at the moment) to find out if accidents rates changed?

What's the argument for motorcycles? Less risk to them from cars I suppose?

You're good at this stuff Bill.. if you are opposed to this (I don't know your stance) then what approach would you take?

TFL did a trial the other year, one of the places was Brixton Road (A23)
Their report on it is here: http://www.tfl.gov.uk/assets/downloads/P2W-in-bus-lanes-study.pdf

There's a bunch of statistics in it that I don't understand, but on accidents there's this:

Conclusions - Impact on Vulnerable Road Users
The VRU casualty number assessments were carried out using four scenarios. Each scenario compared the trial against both types of control, resulting in eight analyses for each VRU group.
The assessment of P2W collision numbers showed six of the eight analyses as being beneficial to the safety of P2W riders and two out of eight showed a disbenefit. All four assessments during operational hours showed a safety benefit.
The pedal cycle casualty numbers showed three of the eight analyses as being beneficial to the safety of pedal cyclists and five out of eight showed a disbenefit. Two of the four assessments during operational hours showed a safety benefit.
The pedestrian casualty numbers showed two of the eight analyses as being beneficial to the safety of pedestrians, five returned a disbenefit and one showed no change.
None of the figures produced are statistically significant.

and on public opinion this:

Customer research carried out on behalf of TfL into the attitudes of a range of road users were made available for this study. Studies targeted motorcyclists, cyclists, bus drivers, pedestrians and the general public.
The surveys showed that only motorcyclists and car drivers (who are not also bus users) as the two user groups where a majority approved of the measure. Amongst the VRU groups, the main reason for disapproval of the measure was their perception of the compromise to safety.
Among a sample of Londoners, more people believe allowing motorbikes to use bus lanes would be a bad idea than a good one, but opinion is strongly divided, with 45% in favour and 48% against.

So TFL under Livingstone rejected it saying there was no proof there'd be any safety benefit to anyone.
