And what is the legal position of a rollerblader/skater on the road? I
suspect that they are not classified as vehicles, in which case if a
hundred or more of them skate through a red light, obstructing the
right of way of pedestrians and vehicles, what are they guilty of?

Knowing this city probably nothing. And they are probably receiving a
grant from some charity or arts council.
If they want to skate together Im sure Westminster Council could close
Green Park every Wednesday for them.
Why exactly do they have to skate on the road? Apart from being able to
be smug in the fact they are causing disruption to us ordinary folk just
trying to get on with our lives.
