VB i CP är något som många andra länder praktiserar (fast då HB i länder med vänstertrafik) och även de uppger att det underlättar och ger mer info tidigare etc.
England
Citat:
When taking an exit to the right or going full circle (unless signs or markings indicate otherwise):
Signal right and approach the exit in the right hand lane
Keep to the right on the roundabout until you need to change lanes to reach your exit
Signal left after you have passed the exit before the one you intend to take

Citat:
Position and signals
Being correctly positioned and signalling clearly in good time helps other road users. Knowing and following the rules improves traffic flow and safety at roundabouts.
While this appendix provides general advice, other factors such as signs, road markings and the position and type of other vehicles can influence the choice of lane.
Where there are signs or road markings which indicate appropriate lanes, these should assume priority over the following procedures.
Correct roundabout procedure
Imagine that you are approaching a busy roundabout with six converging roads. Follow the advice in the diagrams and:
•treat the roundabout as if it were a clock face
•all movement on roundabouts is clockwise
•always assume that your approach is from the six o’clock position
•approach at the correct speed and in the right gear
•always signal your intentions clearly
•if there is no traffic at or on the roundabout you may take the shortest and most convenient route through it
•cancel your signal after leaving the roundabout
Now that you know the rules, show a good example to other drivers by following them every time. They may even copy your driving style and do it right too!
Och kollar ni bildexempel 4-5 i länken så visar de att HB (vänstertrafik) ska användas så som körskolor här hemma lär ut att VB kan användas.

Frankrike menar att VB i CP är bra och lär ut det… (jag har i citaten översatt till engelska)
Citat:
Turn signals and change of direction on the roundabout
The roundabouts are one-way but the use of turn signals is necessary for other motorists to be informed of your intentions.
A left turn signal, although not mandatory, makes it possible to mean that you remain on the ring of the roundabout.
A right turn signal indicates that we are about to go out.

Citat:
Flashing to take a roundabout
•If I take the first exit on the right, I turn on the right turn signal before approaching the crossroads.
•If I continue straight, opposite, I turn on the right turn signal at the height of the previous exit.
•If I take a left exit or if I turn around, I turn on the left turn signal before approaching the crossroads to show that I will turn left.
•Whatever the direction taken, before leaving the roundabout, I always turn on the right turn signal.

Italien gillar VB i CP och lär ut det…
Citat:
In the event that the vehicle intends to use the roundabout to turn left or make a U-turn, it is necessary to activate the left arrow at the entrance to the roundabout, keeping it active as long as you are driving in the left (central) lane of the roundabout. Before taking the exit, you will have to activate the right direction indicator sufficiently in advance, to move in the outer lane paying attention to the arriving vehicles, and exit the roundabout

Skal du ut til venstre
Du kan hjelpe andre trafikanter ved å blinke til venstre før du kjører inn i rundkjøringen. Begynn å blinke til høyre når du er på høyde med siste utkjøring før du kjører ut.
Spesielt når du skal til venstre i mindre rundkjøringer med god oversikt, kan du hjelpe andre trafikanter ved å blinke til venstre før rundkjøringen.
