Research direction
Start by reproducing the walking and cycling examples from the linked CodePen pages with the Mapbox Directions API on Android. Compare the behavior with the linked OpenStreetMap route and verify whether walkwaybias=1 and alleybias=1 are being applied. Done means identifying an actionable cause or confirmed limitation and documenting the expected routing behavior.

Description
Hi all-
I am using turn-by-turn navigation with the Mapbox DirectionsAPI on Android and explore strange routing behavior when selecting the "walking" profile. Some routes are 3x longer than a comparable cycling route, especially highway=path and =footway seem to be avoided at all cost. I also pass walkwaybias=1 and alleybias=1 but it does not change the behavior.
An example here:
- Walking Route: https://codepen.io/ulnn/pen/RwrYbja
- Cycling Route (better route, but still mediocre): https://codepen.io/ulnn/pen/eYJLOKb
- Best Route (desired outcome): https://www.openstreetmap.org/directions?engine=graphhopper_foot&route=50.13981%2C8.69852%3B50.13825%2C8.69507#map=18/50.13921/8.69745
