A good ethos for accessible design is that making designs accessible and inclusive often the raises the bar for the average non-disabled user.
99% invisible has a good podcast on this with the development of the curb-cut. Oriignally it was for wheelchairs but it turns out to help parents with strollers as well!
Also love to point to the disability persona spectrum. Shows how disabilities can vary from permanent, temporary, and situational. I think the Microsoft's Inclusive Design Toolkit is partly responsible for it (but doesn't appear in the deck).
