Also, some people who are wheelchair users, who require an accessible wheelchair stall, experience severe autonomic dysreflexia if they are unable to empty their bladder and/or bowels right away! Trust me, it is just about the worst feeling in the world: https://en.wikipedia.org/wiki/Autonomic_dysreflexia https://en.wikipedia.org/wiki/Autonomic_dysreflexia There is nothing like the feeling of your head about to explode, plus the worst feeling of doom possible, plus your blood pressure surging, and seeing spots. Afterwards, even after you relieve yourself, you are completely washed out and feel terrible for the rest of the day. Like "I got run over by a truck terrible" (no exaggeration). By the way, there are people who can walk who experience this too. So don't just assume that it is only wheelchair users who experience it. Just know that restrooms/toilets/bathrooms, especially accessible stalls, need to be open to the public, not only for human dignity, but for the small subset of people who absolutely have to relieve themselves at any given moment. It is, no question, life threatening. It is actually shocking that the general public does not realize this. The same goes with the fact that wheelchair and/or mobility device users definitely require disabled parking for safety reasons, as they can easily be in a driver's blind spot.
