Huh. I'm Irish; it would never occur to me to try this. Buses will sometimes delay departure if someone is visibly running for the stop, but that's as far as it goes.

I think maybe France might be an outlier there. Honestly, opening the door in random places seems kind of unsafe.

EDIT: As people are doing stories of public transport in different countries, here's mine. I was getting the BART in San Francisco carrying luggage. The driver _leaned out the window_ to warn me that this one wasn't going to the airport. As it happened, that was what I was going for; I was going elsewhere and then on to the airport later. But it was nice of her to check (and very unusual; don't think I've been anywhere else where train drivers interact with the public at all). Always think about that when I hear people complaining about San Francisco.
