Well that would still be covered by the one long vehicle rule

There is no such rule in law. A body of skaters is not a vehicle. You are
merely following advice from the police on how to behave; presumably they
don't want to invest the effort in policing it properly. Anyway, a
pedestrian trying to cross the road is not aware of this "rule".

What happens at zebra crossings by the way?

but yes, the skate is insured. The t-shirts available on the
website and before the skate help fund the insurance.

Glad to hear it.
