Are you just talking about being able to make a lane change within the roundabout? Because the outer lane cannot take the third exit in your example (at least according to the lane markings), they must exit before then.

In Ontario anyway, the general rule for roundabouts is that you aren't allowed to make lane changes, though they still use a dotted line so as to not make you think you're prevented from entering the inner lane.

Edit: I see it now. Took me a while to see how the inside lane stops at two spots. Interesting design. It ensures that you're only crossing traffic when entering, not when leaving, at the expense of it being less flexible (note how in two directions the right lane cannot be used to go straight through, so signing clearly in advance is much more important).

On these "turbo roundabouts" there are also kerbstones between the lanes, not just lines. You can cross them but it'll be obvious that was not the intended use.

I hate driving them. Somehow every one I drive on seems massively overengineered, and could have been done with a completely normal single lane roundabout. But it's usually not rush hour when I drive there.
