One thing I noticed about the video introduction is the speaker is explicitly talking to the viewer as if he or she is not the target audience, e.g. "while you and I may take this for granted ..." and "the disabled are exactly the same as you and me ..."
And I guess that for a disabled person it would be a huge psychological win to have able-bodied people looking with envy rather than sympathy at their means of locomotion.
If you lived in a warm climate and work was 10km or less away with bike lanes........this would appear to be an interesting choice? Or worked on a large warehouse floor where you constantly moved between areas etc.
I think this video is aimed at reaching out to the people around the disabled person who might currently be adapting their lifestyle to suit the requirements of the disabled's present assistive device, and could be convinced to advocate to the disabled person based on the increased autonomy/decreased dependence it would lend them.
