FWIW, cycle hopping tends to give you more forward control (you can stop immediately by jumping down, and this is a faster reaction than braking) but less sideways control (although you're likely to tip in a way that you land on your feet). I personally only ever use it as part of a running dismount, approaching a kerb (so I can hop straight off).
Not sure why there's any value in waiting until you're outside the station to unfold a folding bike. The bulk and slow progress in carrying one is likely to be more hindrance in a crowd than the unfolded bike (and certainly where I commute, full-size bikes are stored halfway up the platform anyway!) The regular folding bike users on my train are sensible enough to unfold behind a pillar or other obstacle so as not to obstruct others.
TBH though, badly behaved cyclists probably wind other cyclists up more than anyone else!
