After getting over the terror that is "first-time experiencing two-lane roundabouts occupied by a lot of people who might need cataract surgery and younger reflexes" - I realized the fully two-lane roundabouts are entirely manageable as long as you pay attention. And as long as YOUR reflexes are better than the other guy's.
What IS a big problem - is the two-lane roundabouts that exit into one lane exits. Imagine the circle - north, south, east, west...
I'm coming FROM the south. Heading West. If it were a normal intersection it'd be a left turn. But it's not a normal intersection. It's a circle. By the time I get to that exit, it is now a right turn.
But I'm coming from the INSIDE lane, because that's the rule. If you are entering a 2-lane roundabout and you're wanting to go to the "third" exit, you have to enter into the inside lane.
And you now have to make a right turn, from the inside lane, into a single lane where people who are coming from the east, and from the north, also exit.
If you're coming from the south, you won't always even SEE someone heading toward that western exit, if they are coming from the north. Because you are entering while looking to your left. And to your left - is the western exit. You're not looking north. You're looking west. Entering from the south, going in a counter-clockwise position.
So that's where I think roundabouts are horribly flawed. Entering a two-lane roundabout with the intention of exiting into a one-lane exit 3/4 of the way around the circle.
