Motorcycles in your bus lane

Yes, motorcyclist do want to ride in bus lanes - petitioning as we speak.
In my view, unless a convincing case can be made that there good grounds to keep them out because of proven risk, it is foolish to needlessly antagonize another group of road-users.

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?
