"Accomodations are for people who need them not a shield for hyper-selfishness", namely people riding bicycles on sidewalks that are seen acting with an insane level entitlement while riding on dedicated walking lanes.

People act as people do regardless of their method of conveyance. A polite way of encountering a group walking where they should (and another should not ride) is to dismount the bicycle, say "excuse me" and walk through, then to remount and continue on the bike. In the case you mentioned, calling out in advance "excuse me, coming through" should just do it. If not, step up to bell ringing.

You should see what cyclists from Austin do on the Texas backroads, with their stopping in the middle of the lane at the top of a hill, doing the same on a tight curve, riding abreast... But again, people are people; they don't seem to realize road signs have a setback for a very good reason.
