if you trim your track inside Strava (because you left the GPS on for the subsequent car/train journey) then none of it appears in any segment leaderboards
I don't think this is true. What does happen is when you trim in Strava (which I do most rides because I don't entirely trust the privacy zone feature) is that it starts recalculating segments and it takes a while to do so; in the interim the ride vanishes from leaderboards, but then comes back once it's recalculated.
I gave up looking at absolute leaderboards long ago, it's all about being second quartile in the male 43-45, 70-80kg, today only filtered leaderboard.
