I don't understand: They get pissy, but you don't find that obnoxious?

If cyclists got off the roads every time a car comes by, that would be consistent with their expectations for walking paths.

No, I'm saying most cyclists are reasonable but I've been on crowded trails with elevation changes where they haven't been and have acted as if they had the right of way and have sometimes gotten pissy if I didn't get out of the way quickly enough.
