And it hasn't stopped since. Fortunately, they are not as big on public
transport in the United States as in Europe, so the announcements don't
happen as frequently.

And you'd blatently end up with "Please stand clear of the doors.
Mind the doors. Doors closing" and such other useless nonsense.
There is a bleeper that quite effectively conveys that information,
just like "ding" is a perfectly clear indication that the bus is
stopping at the next stop.

If there is one thing that seriously grates on the Tube, it's the
continuous announcements on the stations when the train is stopped
there. None of them are necessary, except possibly stating once only
where the train is going for the benefit of the blind/partially
sighted. The Met line, for some reason, is the absolute worst for
this, particularly the announcer at Farringdon who just can't shut up.
