Two-lane roundabouts

Why are there two-lane roundabouts EVERYWHERE in Orleans? I have NO CLUE how those work. Why would you ever want to be in the inner-most lane? And it's not like you can avoid them or turn back around when you see one coming up. All of a sudden, you're there and there's no way out but through (We can't go over it. We can't go under it. Oh no! We've got to go through it!). I just yield until there's no one there and then book it. I've seen the reels where people get T-boned on those roundabouts. That's NOT going to be me!
