real talk, I think the stop signs are a large part of the problem. Roundabouts are supposed to slow people down, but stop signs make them think "stop and then go go go"

Roundabouts aren't supposed to have stop signs. The whole point of them is that they don't

or "vous n'avez pas la priorité" as they say in France (since roundabouts invert the usual rule that at an unsigned intersection you must yield to traffic to your right)
