- i.e. priority only exists once there is a vehicle on the roundabout.

True, but it's like a pedestrian crossing where the official rules are
that you only have to stop when someone has actually set foot on the
crossing. In the *real* world you need to anticipate when the car (in
the case of a mini roundabout) or pedestrian (in the case of a zebra) is
about to do so, and slow down in anticipation - or keep going at the
same speed (without accelerating) if you judge that you will not make
the car/person have to change speed/course, and will be clear of their
path by the time they arrive.

Not quite the same though. If you driving onto a mini-roundabout means
that someone approaching on your right, but not yet on the roundabout
has to brake or even stop, that is just as legitimate as you doing so
for them, as no priority exists. Of course you have to be aware of their
proximity and approach speed and may well decide that asserting your
right to continue is not sensible.
