My current speculation is that the time it takes to wait a an intersection is overestimated. Gard from Norway has added an improvement which I'm trying out here: cdc844d

Estimation: 1/2/1 days

This seems to be due to the differing maxspeeds:

• Seestraße has maxspeed=70
• K 1068 and K 1081 has maxspeed=100

Google Maps also has the switching point between the two paths on Zeppelinstraße nearby, on the other side of Mühlstraße.
