They most certainly do. I really like them, and there are a few over here in Norway as well, where they have replaced four-way priority-from-the-right intersections. Many 80 km/h rural roads aren't yellow-diamond priority roads and roundabouts are quite clearly safer than x-junctions. It has been proposed to make all rural roads priority roads, but it hasn't happened yet. In the mean time, mini roundabouts are a quick and sensible fix.

Roundabouts are great when there are not that many cars

However, if there's just too much and too many vehicles inside-and-out, then these things become 'circles of hell' (like this one in Indonesia)

They did this one because it's the main roundabout to a large new residential quarter located north of Madrid, as they estimated back in 2007 that the population will reach up to 40.000 inhabitants, but then the Spaniard economic collapse came in 2008, which mean that it nowadays still go throug the motion so there will spend so many years to get the whole quarter full so far.

Anyway, I never have seen another one like this in Spain.

Does any one know how many lanes has the World's widest lane-marked roundabout?

I've driven here more than thrice now (QMC Eliptical Road) and I love the fact that it has so many lanes.

In Spain bigger cities tend to have even 6-7 lanes, in Madrid I think it is even more with 8+8-laned avenues in the Southern part of the Center, for example.

AFAIK, the theory and mode of operation here in the Quezon City Elliptical Road is that at least 3 lanes are inner lanes (e.g. lanes closest to the inner circle aka Quezon City Memorial Park), the other 4 lanes are exit lanes if you want to exit the circle and 1 lane is said to be allocated for bicycles, motorbikes, tricycles and pedicabs (aka 'padyak' in the local language).

Of course, here in the Philippines, theory is vastly different from execution as most drivers will just travel in any lane and do a free-for-all.

Also, the concept of 'right-of-way' here in this country = I AM ALWAYS RIGHT!!!

This Ann Arbor, Michigan roundabout had the most crashes of any intersection in the entire state of Michigan for 2014 (170 crashes).

Interesting enough, the Transportation Research Institute of the University of Michigan in Ann Arbor is widely known for its work on the area of traffic safety.

A couple of features makes this Ann Arbor roundabout different from the Dutch ones.

First of all, it is designed in a way that makes speeding across the roundabout easy. Some through routes can probably driven in excess of 30 or even maybe 40 miles an hour. Also, unregulated pedestrian crossings are generally not recommended at high-speed arterials with 2 or more lanes in each direction. In addition, it's a multilane roundabout. These cause less predictable behavior than on turbo roundabouts (i.e. people changing lanes) and the capacity is used less efficiently (people going through or left only taking the outer lane).

Today a baloon had to make an emergency landing in the middle of the largest Slovenian roundabout (Tomačevo in Ljubljana). There's also an expressway underneath it.
