And sometimes seriously non-trivial. When there is a substantial elevation difference you need a lot of ramp--which needs a lot of space. We already are seeing the problem with road construction--cities avoiding doing work that would require bringing the sidewalks up to current standards. I don't know what the issue is but those curb cuts for wheelchairs are labor intensive.
