Also it would be wonderful if stores could have ‘sensory friendly’ hours for autistic people/families with autistic relatives. Reduced crowds, no music, that sort of thing. I’m autistic myself, and going shopping can leave me in tears sometimes.
As for wheelchair accessibility, I use a manual wheelchair, and I find I have a hard time getting around. Sidewalks are cracked and dangerous, door thresholds are too high, and sometimes doors themselves are too narrow. I know not much can be done about the last one, but it’s a good thing to keep in mind for any future buildings.
There are lots of other ways to make things more accessible, but I think this is a good place to start.
