so-called Start Custom Session Route 6 Eglundsdorf to Schmiedgasse vanilla test run end-to-end in ULF A1 with one custom choice of 10:14 departure. There is a subtle issue in the initial transition from 20 kph to 50 kph but it is really pointless to test using F4 for an external view as the route is abandoned early on as major crossing after major crossing at limit of 20 kph occur in silence, vibration free. So this simple test was never done, or if done, the issues were not addressed. I suspect the dev has no adequate trouble ticket tracking. That is just my guess. Or the code is spaghetti or worse..
