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?

I would suggest they are guilty of using an ecologically sound form of
transport that if more widely adopted would resolve London's traffic
congestion problems at a stroke. Of course things would need to be better
organised so that those vehicles with a provable need to be in central
London could claim a percentage of their Congestion Charge back. The CC
having been raised to (say) £50.
