Possibly, if all travellers were sensible RailUK members
, or maybe in a different world where people naturally put the collective good before individual advantage. In this world the platform passengers would not all stand back, would not all leave a path for departing passengers, would not all wait for the train to be cleaned...
It's probably better to think of the passengers as young children and the train seat/luggage space as a free sweet shop and plan your crowd control around that!
Note: I put myself in the 'Individual Advantage' class as I use RTT to get an advantage.
