Has the give-way-to-traffic-on-the-right rule on roundabouts always
applied?

I think that rule was made firm under Barbara Castle. BICBW.

So who was defined to have priority over whom before Barbara Castle? Was it
one of those dreaded cases (which are now very rare) where no-one had
priority and it was a free-for-all, based on politeness. If there was no
defined priority from the right at a roundabout, then I can imagine it would
lead to all the faffing around and stopping on the middle of a roundabout
that we saw in the IAM video.
