How about trips out that aren't for hospital visits? Going to and from work, perhaps, or even (Heaven forfend!) going out on social occasions sometimes?
A few years back, the then government cut the criteria for PIP HRM from being able to reliably walk 50m down to 20m. A large number of people lost their PIP award and, therefore, their Motability car as a result. A great many of these had relied on the car to enable them to work.
I remember hearing of one woman, but she will have been one of many, who was given support from Access to Work, to allow her to continue in employment. They agreed to pay for a taxi to and from work. This cost about the same, per day, as her Motability car had cost per week, while giving her far less in the way of independence as, of course, it only allowed for trips to and from work.
