Perfectly healthy peds who take the curb cuts. Used a bikeshare to go to the Metro today and had to wait in the crosswalk for a perfectly fine 20-something to walk down the curb so I could go up it to the dock(parked cars blocked it from the street,and I'm not trying to bunny hop one of these tanks). On my old commute route,I used to use crosswalks to go around a sketchy traffic circle(we do not do them right in DC) by AU,and would constantly have kids step in front of me on the lip of the ramp. Not only was it rude,but it was stupid,because every once in a blue moon a car would take the turn at speed and roll over the edge of the ramp's lip. I've no issue with folks who need them using them,but able-bodied people should have no problem with stepped off a curb.
