It's more a poor place for a roundabout. It was a very busy intersection in one direction, where the switch to roundabouts meant there was no longer a break in traffic. What it needed was a light with a sensor to let the very sporadic side traffic through (technically, a roundabout can have this, but the 3/4-way intersection that's always green except when someone needs it to not be is better), what we got was an endless stream of cars blocking the way for a lot of the day. If you pull in after the car already in the roundabout passes by, you get hit by the next one.
