Yeah, exactly, we never indicate left (your right).

I mean, I don't particularly love our system, especially when turning into a roundabout and there's a car coming up to the exit that you want to enter from, then there's no way to tell, whether they'll take that exit or not, until quite late, because their indicator light is facing away from you.

But yeah, it feels like the system you described would fall apart rather quickly, too, with multi-lane roundabouts or just oddly shaped roundabouts where, for example, you could interpret them as a T-junction or not.
