Just a different perspective - there's so many 16s that go to different places. If you were trying to get to Culmore (16F) you probably wouldn't want to get on the 16A (Annandale). I hate it when I'm on the 16Y and people are flagging it down and then don't get on because it doesn't go to their destination. People have written to Dr Gridlock about this, too, whether the bus should stop at every single stop when there are multiple busses coming to the location. Generally, the busses will get more and more off schedule and back up traffic, and the consensus is that people waiting should be mindful and step up to the signpost when the bus is coming.

I've certainly seen 16s leave people behind, I only feel bad when those people are up and active at the stop. When someone is just sitting in a bus shelter, I wouldn't assume they wanted to get on a bus either. When I lived in Portland and exclusively rode the bus, that's how it worked - if you were back in the shelter, the bus wasn't stopping.

While I feel bad for her, having fallen in front of people, and the risk of damaging a laptop ... on most busses, if the driver waited for everyone to sit down, the bus would never move. Not for lack of seats (sometimes) but the longer the bus is sitting there, the better the chance someone else is going to come running down the street, waving their hands, begging the bus to pause for them. Vicious cycle. Plus, a lot of people (not necessarily the woman in question) dwaddle when looking for a seat - rather than taking the first available seat, or quickly moving to the back, they ponder the seatmate, look for a window seat, don't want to sit too close to the back door...
