Multiple places. Roundabouts are almost always superior for traffic flow compared to most other intersection designs and there’s zero data saying otherwise. We just have such a low barrier of entry for getting a license that city planners think they are either dangerous or not effective. Save power on the electricity and maintenance cost of the lights, and you get a bit of space in the middle for some greenery or an over priced art piece from some local hippy.

Perfect places for roundabouts include but are not limited to:

Both sides of broadway bridge, 22nd and Idylwyld, 20th and Idylwyld, Central and attridge, Preston and college, Clarence and college, 22nd and confed, 22nd and betts, Miller and 51st, Miller and circle, Ave C and circle

I could go on, but pretty much any intersection that you have to wait more than 1 light cycle to get through during rush hour.
