How does https://cycle.travel/map/ perform routing-wise in Amsterdam? (Unaffiliated happy user.)
Maybe slightly better, but still not great. It's skipping the eastern part of the Sarphatistraat. Also it struggles with street names and encourages you to only type a town, which isn't very useful. I like that it allows you to choose between paved, gravel or any. Although gravel may still be too limited for some; mountainbikers like dirt tracks, and I've had Google Maps send me through loose sand that would probably…
Oh, good spot. Fixed. OSM geocoding is better than it used to be - I used to just say "town" because streetnames were partial, but they're pretty good now.
If you have a start and endpoint that should use Sarphatistraat but don't, I'm all ears. (It's my site!)
