I dont know what article you are reading, but the one referenced revolved around a single instance of temporary (albeit dangerous) inconvenience. If she was denied the use of a wheelchair altogether, I might see your point. But as others have stated, 100% access is not realistic given the current technology for disabled people.

Maybe instead of regulation and lawsuits, people that are so worked up over this issue should actually try to invent better tech, instead of expecting the govt to solve all our problems and compensate them whenever we dont meet 100% perfection.
