I'll check it again but white arrow, on roundabouts, only shows where to enter while you're approaching to roundabout, and, when you're inside it, shows when to exit.
Personally, I prefer the white arrow shows all in same time: Where to enter and where to exit.
Looking screen while you're inside roundabout is not the best you can do.
This can be applied also to those turns than are too close one from two.
