In Waterloo Region I used to cycle through multiple intersections that were "upgraded" some years ago from conventional stoplights to roundabouts and imo it was a huge downgrade to my sense of safety. I went from having a clear right of way (hand signal, cross in the crosswalk) to feeling completely invisible to cars, essentially dashing across the road in the gaps in traffic as if I was jaywalking.

I could handle it as an adult just walking my bike but it would be a nightmare for someone pushing a stroller or dependent on a mobility device.
