Europe has an algorithm that, on such intersections, you have to yield to a car on your right-hand side. This works well until there's a car on every leg of the intersection, which is extremely rare (because, on intersections with such levels of traffic, there are road signs explicitly saying which road has to yield to which one).

Yes, in the US the rules are like this:

- first to the intersection has the right of way. - if you both arrive at the same time, the one to the right has the right of way. - If you both arrive at the same time facing each other you can both proceed driving straight or turn right. - If you both arrive at the same time facing each other anyone turning left must defer to the other.
