Do make sure you are visible and can wave down the driver if they don't see you at the stop- if there is no one there they will keep going. I had a couple buses ignore me some years back and ever since i always give them a friendly wave if i don't see them put the turn signal on to pull up to the stop I'm at. I imagine this could be harder and require more planning if you're shorter and can't get out into the street with the curb drop bc of wheelchair.
