Dangerous pedestrian crossing
That's why we make it easy to tweak existing profiles via our GraphHopper Maps website or insert via points etc...
This is now fixed and deployed. See the route here and the specific fixed examples here. Note that you can still find the dangerous spots via clicking the "stop" icon below the route information multiple times. But this is likely a result of the bad cycling infrastruture as cycle.travel contains these short dangerous parts too and if you do such longer routes for Germany it does not happen.
