E.g. in the Netherlands or Germany there's no need for 4-way stops and such. If no other signage applies, then whoever is on the "right" side has priority over the people on the "left" side. And exceptions do apply, i.e. it's not "that simple" either. It does depend on whether both roads are on the same level or not. A road to your right that has a sidewalk border stone running across it does not give them the right of way, while if the sidewalk border stops and both roads intersect directly at the same level, then the road to your right does have right of way.
So e.g. if you take a typical urban development with lots of little streets and houses, where you'd see a lot of rolling stops in America, nobody's gonna stop at every intersection, rolling or not there. This does go as far as when cars from all directions arrive at the same time, then nobody has automatic right of way and one of them has to wave the person to their right through and will be the last allowed to proceed.
