the key difference between this issue and the mentioned duplicate is that you can get out of vehicles, BUT, not with the appropiate action.
observed: as a driver stopping the car you push the button, you "eject", but the engine is still running.
since the car is holding there is no need to quickly get out of the vehicle and let the car with a running engine.
expected: as a driver stopping the car you push the button, you "eject", but
the engine is turned off.
