> Your logic applies equally to roads as it does to sidewalks, so should we just give up on them as well?

No, but I wouldn't drive a low-riding sports car if I lived in an area with crappy roads. I'd buy a pickup truck with good suspension and large knobby tires.

The problem is that accessibility devices don't have the option of "good suspension and large knobby tires".

Every problem that woman experiences is because her wheelchair is not built for the environment she operates in. We need better wheelchairs. Yelling at local state government to fix sidewalks will not work. There are millions of miles of sidewalks to fix and hundreds of thousands of people responsible for them. You can't change that quickly. But you can build a better wheelchair.
