>>1102430>>1102431Is the two-lane roundabout really necessary?
From real-world experience those only create confusion, and the only [spoiler:lit][/spoiler:lit]case where a car enters it is to turn left, (or turn around but that's really rare).
So when you enter the outer lane with a car moving in the inner one, it's pretty much guaranteed he's gonna want to leave at the next exit while you want to stay on the roundabout.
