#12On the other hand, I wonder if OSM's accuracy in Europe has taken a hit in the last year. The lockdowns have led to a wave of bankruptcies of restaurants and fitness centers in several countries, but because mappers are forced to stay home and aren't circulating in the city doing their business, they aren't noticing so much what has changed and removing those POIs from the map. Also, the extremely strict lockdowns in some countries have prevented people from going out for mapping expeditions in the surrounding regions to add missing infrastructure.

#13What is the barrier to adding more data? Do they need funds to purchase it from satellite providers?
they need more contributors...

#14Lyft has access to some pretty good data on where the roads actually are and if there are any closures. Looks like they are already contributing back, which is awesome. Something I've never heard being done, but could be very helpful for cities, is tracking the bumpiness of roads as a metric for road quality. The city could have near real time access to information on where the potholes are. I'd think they'd be willing to pay for it.

#15Except my street. No matter how many times I email Lyft support, it always sends them the wrong place. Most Lyft drivers don't read the directions on pickup either explaining the problem. /sigh #FirstWorldProblems
Have you tried fixing the map yourself? It's easy, just like Wikipedia.

#16I used OSM as turn-by turn loaded into my Garmin [1] for my three year drive around Africa, and then to cross North America six times in 2019. I have been utterly staggered how accurate and complete it is in every conceivable scenario - dirt street villages in Sudan and Mali, capital cities in same, capital cities in South Africa and all over the US and Canada. I also used it to drive down through Southern Europe, to…
I am glad to hear that you found it accurate and complete. I know a lot of mapping of sub-Saharan Africa has been done by foreign armchair mappers working from aerial imagery for e.g. a HOT effort. I myself did a great deal of aerial mapping West African villages in preparation for a trip through the region that I ultimately had to cancel, and I was nervous that without being able to actually verify my edits firsthand, I was introducing some errors.

#17"Road directionality" being only 98.9% accurate seems to be a huge problem for a navigation app!

There's a lot of humanitarian groups contributing to OSM. Usually they get to work after natural disasters, so that emergency workers can get around easier.

No bothersome problem is too small! If you'd like to share, we would be eager to look into this. Reach us through the app or at osm-questions [a] lyft.com.

Road directionality is variable over time. I'm not sure at what rate it changes but I bet it's a lot more than 1.1% per year.
