That's because the car-end doors can be opened by passengers. On Line
14 in Paris, there are full-width gangways between cars, so there's no
risk of a passenger getting on to the track. (And on other lines with
older stock, it needs the Métro equivalent of a J-door key to open the
car-end doors.)

So how do the passengers get out in an emergency?
