Pure Quality of Life thing, and admittedly pretty trivial (so I await the flames lol). But since there are no physical handle notches etc to guide us ... would it be possible to add perhaps a 1-2 second delay of "whoops" time to let us quickly UN-do emergency application if we happen to inadvertently slide the handle to that position? Thanks!
There is generally a bit of resistance on the emergency notches to avoid the situation in the first place. Having a fake 1-2 second delay on BCP would brake immersion, especially considering many trains will pull themselves out of the application without needing a full stop (early westcode, some German EMUs etc).
