By comparison, a smallish concentric marked roundabout has traffic
entering and leaving in all directions, often without signals, short
weaving zones, and highly variable traffic speeds, which I view as
involving a much higher workload.

Can agree on that, and in France the common signal to go straight on (for
exit 2) is to signal as though going all the way round until they reach the
exit

The Highway Code used to give that as the way to signal at roundabouts,
so you sometimes see it in Britain too.

A friend of mine does that. I've never plucked up the courage to ask him
why. I did once query his use of sidelights at dusk, but it didn't get
me anywhere.
