Re: Driving licences?
An example, from my early days making internal Government systems more accessible, is severe RSI; although often not severe enough to warrant appearing on the Register of People with Disabilities.
Often users would struggle to use a keyboard or mouse for any length of time, but could sucessfully use voice recognition software to input data and control applications.
A badly designed form where you couldn't tab between fields or select options using the first letter of the name was nigh impossible to use with voice recognition. A little pressure from their unions, and *a lot* of resistance from a well known blind MP at the time, and I was called in to fix it!
Needless to say the RSI would not have prevented any of them from driving!
