That's not the issue. Union Square on the Park Avenue line and the old South Ferry on the 7th Avenue line both had platform "gap fillers" installed decades ago that require the train to stop at an exact location each and every time: https://www.atlasobscura.com/places/14th-street-union-square-moving-platforms https://www.atlasobscura.com/places/14th-street-union-square... Every station has lining boards that the conductor must check before opening the doors to ensure that the entire train is stopped along the platform: https://www.topic.com/conduct-yourself https://www.topic.com/conduct-yourself

London's Jubilee line extension had platform doors since it was opened in December 1999, but the upgrade to automatic train operation wasn't completed until 2011. So for a long time, drivers had to manually stop the train at alignment points. This did cause occasional delays and problems, but it wasn't unworkable. As a passenger you did sometimes notice that the train doors weren't aligned perfectly with the platform doors. Now days, of course, it stops perfectly every time.
