Well, there are numerous intersections which are mapped as ways, not as nodes.

As mentioned before (with respect to the Magic Roundabout, but it
occurs in many other places), what is one supposed to do when there is
a mini-roundabout at the intersection of a dual carriageway?
Intersections of dual carriageways are generally mapped as ways, not
nodes.

That intersection is drawn as a square, but in reality you can drive
in the middle.
