Where i lived in Indiana (Carmel), there were a ton of roundabouts instead of four way stops or stoplights. I loved them. Less wait time than a stoplight and you can just cruise on when no one is there, as opposed to a stop sign where (legally) you have to stop regardless.
Give me a roundabout any day of the week.
This. Admittedly they will take some time for everyone to fully understand them, but they are more efficient. Nothing is more stupid than stopping and waiting at a stoplight at oh-dark-thirty when there isn't a soul around. A little known fact is that many states allowed right turns on red for the first time during WWII as a fuel saving measure. Fuel is wasted idling at stoplights waiting for non-existant traffic to pass.
