Many of those physically challenged go to great extremes to prove that they can do as much as any one else(possiibly attempting to prove it to themselves as well).
Can see a use for it as well,Marshall University(we are Marshall) being not a small campus,one could easily find their street and building the next class was in.
For a newcomer with a good set of legs its isnt easy,not that many have motorised chairs,many still have manual as have arm usage.But can see a complete parapalegic using a pensil in his mouth to operate one of these,and put to good use I might add.
They have in house attendants but at the door that stops,unless they have guide dog.
We had an entire lower wing in Holdery hall of challenged students,and some in Laidley Hall as it was female.
People who lack certain things like eye sight,motor functions tend to develop other things or whats left.
As for the mount it was a great idea,try wheeling yourself around on say university of columbus to get to a class on the other side somewhere but you dont know where.Many of these campuses including dorms are about 2 sq miles.
The satalite businesses that exist because of it create another 2 miles or more.
Just because you or your life exists in a smaller area does not mean its not usefull,when limited in capability any ease or help is a great gain.
A battery operated chair can actually have its charge run out in one day.
I know what your thinking ,I wouldnt want to go through life like that,they do as well as they pick up on emotions,expressions quicker than you or I,but they didnt get a choice generally.
There is hope a complete paraplegic who graduated using a penil sharpening his mind,got a job paying 5 times more than I did.My base when retired was 36 k a year.
