Yes! I've driven a lot in France where at least in smaller cities there are way fewer signals and stop signs than on North America. Like a lot of trips you don't encounter any. Traffic is managed by roundabouts and priority to the right. The consequence is you have to watch what other cars are doing and actively drive.
When traffic signals mediate everything for you, it's much easier to turn your brain off and when something unexpected, like a pedestrian crossing the road occurs, you don't see them because you're only watching the signals.
The added benefit is much better traffic flow. I wish we could get more roundabouts, unfortunately I think it would be a tough transition.
