No clue. Here in Germany it’s just fine. I’ve been using OSM data forever and it regularly gets me where I need to go. Also like the bicycle routes. Routing isn’t perfect with those, but close enough, considering the proprietary apps aren’t perfect either. And with OSM you also get people’s favorite illegal mountain bike tracks and all those awesome details.

Only issue I’m having is all the construction work and traffic jams these days, so you really want some live traffic data while navigating the car across cities.
