...one of the towns here north of Tucson just recently installed one of those "round-abouts" on a fairly heavily traveled secondary road with VERY interesting results!
...no true "accidents" yet, but there are literally hundreds of black skid marks on ALL four of the approaching roads and marks ALL over both the "center" and "outside" curbings...because what USED to be an almost 'square' intersection is NOW an 'outside' circular loop...sorta like having to make a righthand turn to make a lefthand exit...duh!
