The "go around again" option is a really great feature of rotaries. While motorcycling in England we weren't sure which smaller road to take from the large rotary in Leeds. So we went around again while my wife unfolded the table sized Michelin road map, and again while I read highway numbers to her. Then happily headed down the road we needed to take. We didn't block up traffic, have to go down a wrong road, bang a u-turn, or all the other problems of traditional intersections. Although I'm sure that we caused some strange looks while riding around in circles with a huge map spread out in the wind.
But the article rightfully points out that the "traditional" American driver will have some serious adjusting to do. Cooperative driving is a must, something we just don't do. Anybody who has been stuck in a traffic jam caused by a highway lane closure has witnessed it. Everybody jams up to the merge point then does the "me first" game. Those that try to merge smoothly and early are rewarded by a pushy jerk that drives around them and roars up to the merge point to try and jam themselves in to line.
Maybe it is a matter of growing up. America isn't a teenager anymore. As a general population I think we need to start thinking more like adults.
