In all the neighborhoods here instead of stop signs at every side street intersection there are round abouts. I dig them, on a moped they are not an issue at all. Saves me so much time commuting, during rush hour its 10x faster than the arterials. They are mostly ok from a safety stand point, except for when people try to take a short cut on their left turn and bypass the round about. A big penske van did it to me the other day and I barely avoided it. Roundabouts arent the problem its the oblivious and selfish drivers. Driving around like its their road, leaving passive aggressive notes on peoples cars who park on the street in "their" spot. I prefer round abouts over unmarked intersections, those are scary.
