As a German, pretty much all of the intersections shown in the article trigger me quite a bit. In Germany, there's a standardized Autobahnkreuz [1] most of the time. If it's a construction site or an incompleted Autobahn intersection, it's usually called Autobahndreieck (and not -kreuz) on the signs.

This way, all drivers can already sort themselves onto the matching lanes without even having seen the signs yet.

The standardized Autobahnkreuz also has always identical ways to change directions, where the left lane leaving the highway is made for change in opposite direction or for turnarounds. So if you took the wrong exit, you can always save yourself by just driving that lane 3 times across the bridge.

If the traffic increases over time, usually the right exit lanes are doubled and that fixes the problem.

Rarely though there's different setups like around the A61 and A67 where the traffic around and towards Frankfurt city / airport is too huge for that system.
