ARGH - I HATE those. Couple those with poor signage and out-of-towners will be lost for, well, if not hours, certainly tens of minutes. :/ (cherry hill ... lost several times in that area and no ways to turn around for miles).
It is a lot better than collisions at lights. A NJ DOT friend says the jughandles are a lot safer-- the principle is keeping stopped and turning cars away from moving traffic.
Would many DOT workers say their systems are stupid? Michigan DOT people probably justify the Michigan Left as safe/efficient/etc, and other places use roundabouts (Camden seems to have removed their roundabout(s) last time I was there).
Also, forcing people to drive an extra 3-4 miles because they missed a turn is probably not very good for the environment. Just sayin'
