Comment from heretofore
Can you comment on why the access=destination tag was removed? The road clearly says it's only for Airport traffic.

Hi, heretofore!
My name is Stepan and I am a mapper on the OSM team at Lyft
Thank you for your question. There is indeed a sign here only for Airport traffic https://www.mapillary.com/app/?pKey=1329286604145674&focus=photo&lat=38.924637887718&lng=-77.196989113286&z=17&x=0.46447061703292597&y=0.483405619346755&zoom=1.6714980385520235. And based on the OSM wiki, it can be assumed that such signs are the reason for adding the access=destination tag. (https://wiki.openstreetmap.org/wiki/Tag:access%3Ddestination)On the other hand, the tag description in the OSM wiki is rather modest and the main focus is placed on local traffic (https://wiki.openstreetmap.org/wiki/Key:access#List_of_possible_values.) In our understanding, the destination access should apply to roads in a specific location, where roads can be used as a destination or a starting point. That is, if we add this tag by sign, then we need to do it for the entire way and for all the airport roads. We came to such conclusions based on our experience in OSM. Motorway and motorway links rarely have destination access in USA and more often the whole location is tagged with access=destination, for example, here almost all roads at the airport have a destination access tag (https://www.openstreetmap.org/way/42789202/history#map=18/28.38059/-81.54990).
Applying this tag only on part of the road makes the road unroutable in OSRM. So that’s why I have decided to remove forementioned tag. Please let me know if you have any further questions or insights that could help me to understand your point in this case.Thank you for your contribution,

Comment from heretofore
Thanks for your reply! I think we have different expectations with respect to
> makes the road unroutable in OSRM.
Routing suggested I take the Dulles Access road when it was NOT my destination, and I had set my options to avoid tolls. After the trip, I went to look up the tagging, which is how I found your changeset.
I understand that you want to make the route available to your drivers when they go to/from the airport, but I would also like not to be routed into a rules-breaking situation. We don't want drivers to be surprised by the suggested route and have to divert dynamically to avoid a traffic violation. This could include Lyft drivers, too.
If successful destination routing requires either a start or end point within continuous destination-tagged roads, perhaps the rest of the airport should also be tagged.
Thank you for your consideration,

Comment from YuliyaShustava_lyft
Hi, heretofore!
My name is Yuliya, and I am a Quality Control lead at the OSM team at Lyft. Thanks for sharing your point of view. We think you’re totally right about the necessity to consider the routing suggestions, when the driver does not plan to go to the airport and is routed into a rules-breaking situation. The option of tagging all the roads at the airport is a fairly massive change and this is a rather rare variant of airport mapping in the USA, so we have opened a discussion of this topic in OSM slack (https://osmus.slack.com/archives/C2VJAJCS0/p1677685654035089). I propose to continue the discussion there. We are sorry in advance for any inconvenience these edits may have caused.
Best regards, Yuliya
