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.
This is downright reactionary thought. I will not stand for this. While all car infrastructure is a bastard, roundabouts are definitely preferable to four-way intersections. They're not just safer for everyone involved, require less infrastructure and are usually quicker no navigate overall - the fact, that they don't necessarily stop traffic makes them more ecological: Not as much breaking/accelerating as a normal intersection. If done right, the middle is also unsealed by asphalt, giving space to a little greenery.
If you're driving in a city that embraced roundabouts a while ago, you basically never have to stop unless you're driving in peak traffic hours.
