Just an anecdote: I use the DLR multiple times per day and after a few years using it I finally got stuck on a door the other day. I pushed the button to open the door, it started opening and when it was around 80% opened, I was entering the carriage, when it suddenly closed really fast. I got sandwiched on my shoulders and then on my right foot. The door didn't open, I had to force myself to remove the damn foot painfully. It did hurt. Can't imagine what could happen if it was someone weaker (like a child or an elderly). Oh, and my red snickers turned black.
