Actual route

The android app gives exactly the same result.

Expected route

The route is correct, but the time it takes is closer to 20 minutes, not 40.

OSRM gives better prediction: https://www.openstreetmap.org/directions?engine=fossgis_osrm_car&route=52.20%2C21.06%3B52.09%2C21.12#map=12/52.1451/21.0866

The bug has been successfully reproduced. To reproduce it, use the following coordinates: 52.20101, 21.05738 for the start and 52.08979, 21.12178 for the destination, then allow the navigation and estimated travel time to calculate.

The result will display a travel time of 39 minutes for a 14-kilometer drive, whereas on OSM, it's only 24 minutes.

I think it's because of large group of traffic signals which adds up to 15 extra min (each signal 15 seconds). Google maps estimates 31 min
