One of Strava's problems is that 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.
(If you trim outside Strava and upload that track then it's all fine.)
So, unintended consequences mean that rather than missing out on the genuine leaderboard entries for the bits they did ride people will leave the non-bike sections in and just ignore them.
Oh I see! Not owning a car, this is not a problem I've had - more the opposite, where the end of the activity contains some walking. I don't care much about that though, so I've never looked at cropping inside of Strava before.
