I've noticed a few odd routing decisions in the navigation algorithm and would like to find out whether it's their router problem or just an outdated map (e.g. someone corrected the problem in the meantime).

Which router do they use?

If it's Graphopper or OSMR, then it's easy to test online. If not, is their router available for testing elsewhere?

Examples of problems include extreme detours for bikes, when there's an obvious direct bike route, ignoring the fact bikes have no turn restriction at a given crossroad and routing them as if they were cars and directing cars off a straight highway for no reason only to make them return to the highway at first opportunity.

accept rate: 100% routes on device and doesn't use any of the hosted routing services. AFAIK there is no "online" version of their algorithm, so IMHO the best course of action would be to report the problems on the issue tracker

Thanks for pointing to the issue tracker! I'll wait for the map update (to exclude the problems have been fixed by edits) and let them know.

(01 Feb '20, 21:45) aneleutheroi gives some background to their routing engine choice. As @simonpoole explains it's their own on-device algorithm.
