What’s wrong with roundabouts? Unless you’re Clark Griswold in London.
Roundabouts are fine...as long as there are no cars around. The one near Costco in Idaho Falls is a perpetual accident waiting to happen. We have some in Chubbuck that are replacements for a 4-way stop. It's actually big enough to be safer than the old 4-way stop. There is a smaller one on Hiline near the I-86 undercrossing. That one is a regular source of accidents. Mostly people going through too fast and going through a chain link fence and over a wall.
