Some people like the roundabout, and some people don't. I don't. We used to have a large traffic circle in Kingston at the Thruway exit. The state spent millions of dollars to turn it into a roundabout - the same thing, only much smaller. Why is smaller bad?
If I want to enter the roundabout, and I see a car entering on my left, I don't have time to enter. There is usually a line of cars entering, so I have a substantial wait. The old circle was large enough that I would have plenty of time to enter the traffic circle. Now, traffic backs up at all the entrances.
The circle is so small that an 18-wheller must use part of both lanes.
Contradicting all logic, cars in the left lane are allowed to make a right turn to enter the Thruway Interstate. I'm usually in that right lane so I can get on the local highway to go home. Every time I get to that point, I hit the brake and look left to see if the car next to me is going to cross in front of me. Yes, there is a big, white arrow in the left lane telling cars that they can cut across the right lane.
Kingston recently converted a regular redlight intersection into a roundabout. Traffic is heavier there, and entering can be a challenge. The pictures show it almost empty. I don't know how they did that.

Traffic intersections work well when streets are arranged in a grid like NYC. Older European cities, and cities like DC, are often arranged in a spoke-and-hub pattern where multiple streets feed into the roundabout. Roundabouts also speed up traffic flow because there are typically no red lights to hold you up when there is no cross traffic.
Take a look at the roundabout around the Arc de Triomphe. Can you imagine a traffic intersection working here! And for those who think European drivers are more polite, check out the traffic inside the roundabout in the picture!!
