That is possible, I also heard of a lot of ignorance on standards (like councils painting what's supposed to be bright yellow tactile tiles on the ground grey to blend into the ground, making them difficult to see for partially sighted people). Although I know of a lot of older buildings impressively retrofitted. I have helped a person in a wheelchair a few times or spent time with them, and you have to navigate the world differently. Even crossing the road on a small market street needs you to find a dipped curb, then rumble across aesthetic cobble paving down the road to find another dipped curb on the other side.
