Hello,
I've found a bug in routing.osm.ch for car-routing:
If there is a highway tagged with "motor_vehicle=delivery",
routing.osm.ch is routing yet via this street.
See this example:
correct routing by http://map.project-osrm.org :
http://map.project-osrm.org/?z=15¢er=46.895349%2C7.491045&loc=46.887827%2C7.496345&loc=46.881154%2C7.482033&hl=en&alt=0
wrong routing by http://routing.osm.ch :
http://routing.osm.ch/?hl=de&loc=46.888634,7.497046&loc=46.880585,7.481735&z=16¢er=46.883889,7.490015&alt=0&df=0&re=1&ly=1312628413
