That is due to the heuristic coefficient of 1.0 that OsmAnd uses. That is way over the top. Search for heuristic coefficients in this group and you will find many posts about it (a lot from me criticizing this ;) and offering modified route xmls).
I use 2 routing xmls. One with a hc=1.2 for big city travel for s little more accuracy. One with a hc=1.5 for long(er) distance travels. I have a spreadsheet with lots of comparisons (every route calculation 3x without cache and then averaged for the final time) See for example two (longer) distance calculations. The calculation differences remain the same on shorter distances, but if it calculatates a route in 3 seconds inside a city or 10 seconds is for me not that important. heuristic coefficient distance (calculated) calc. travel time (hours minutes) calculation time minutes/seconds) Remarks Zwolle, Nl - Puttgarden ferry, Ge lot of motorway/highway hc=1.0 487km 4h57m 1m58s hc=1.2 487km 4h57m 19s hc=1.5 487km 4h57m 7s Zwolle - Machiel Vrijenhoeklaan 354, The Hague, Nl first and last part quite some "in city" routing hc=1.0 169km 2h4m 1m21s hc=1.2 169km 2h4m 11s hc=1.5 169km 2h4m 5s Note that for in-city routing I always use OsmAnd as it calculates the best estimated arrival times and routes as it uses its time penalties for crossroads, traffic lights, etc. My spreadsheet contains many more lines of comparable calculations in several countries, road-types, straight-on routes, routes with lots of parallel route options, routes with much in-city traffic, etc. They continuously show to me (prove to me) that an hc=1.5 is good for longer distance and 1.2 is optimal for big city traffic.
