Roundabouts have a bad reputation in America because so many of the roundabouts in America are poorly designed. There are 3 in my county, on a road created so semis don't have to drive through downtown the others are on a highway exit next to the largest truck stop in the area, none of them are large enough for a semi to go through without the trailer jumping the curb and crushing the plants in the middle.
There are 3 roundabouts within 10 miles of where I live. Why do we need more?
Roundabouts have consistently fewer casualties, and usually better traffic flow. Those seem like valid reasons to me.
Got it so round abouts everywhere!!!
Ever visited the Netherlands? Almost all urban intersections are roundabouts. It works.
I have roundabouts near me, I used to be for them until I rode my bike through them. Never again. The problem is cars, not the type of intersection.
Unless I can carry 5 gallons of paint and all my tools on a bicycle, it doesn't really matter. Roads are necessary.
That's actually quite doable, see "cargo bikes". Also, cultural change takes time, I'm not suggesting we junk all cars and raze all roads immediately.
Neat vids from youtube or wherever. Rules later
