Roundabouts are generally pretty shit for pedestrians and cyclists, yeah. Also, they are way more of a pain in the ass to drive in than a regular intersection. I'm yet to see a single example of a roundabout making an intersection easier to maneuver.
EDIT: I don't actually agree with this sentiment. I copy and pasted this from something someone said on donoteat01's Discord server. I just wanted to start a struggle session.
If you mean that you just went a full circle to get back to the road you entered on, that's perfectly fine and legal to do.
Pretty sure I just cut clear across the lanes of traffic lol
Oh yeah that's probably not okay lol. Basically you want to stay in the lane you entered on, until you get to the exit you want.
