IMO ADA is probably a net harm at this point. When I look at the sidewalks here in socal, where 50 years ago they planted these rooty trees that make the region look like a tony hawk game today versus something you'd be able to get a wheelchair across, I'm starting to suspect its all ironically ADA's fault. They put the costs to meet their criteria so high that cities find it a better bet to just absorb lawsuits and not do anything than to actually make their cities manageable for disabled people. We need a more practical ada, that isn't nearly so costly to implement, so cities don't find it financially sensible to just sit on their hands forever.
