I'm not ashamed to admit that I HATED roundabouts for the longest time.

When I lived in Iowa, I avoided these traffic circles like the plague.

There's a series of roundabouts near the grocery store closest to my old apartment. Any time I had to get groceries, I would drive TEN minutes out of the way so I wouldn't have to deal with them.

After a couple of months of living there I slowly started to love them. Now, if I had to choose between a traffic light or a roundabout, I'm choosing the latter!

Roundabouts rock!
