The Blue Badge is actually a picture ID inside a large wallet that you display on the dash board, putting in the date and time you have entered a disabled parking space.

It can be transferred from car to car for good reason, because some holders are dependent on a number of carer/drivers.

The problem is that county councils can change the parameters of the assessment, which I don't think is fair. Also what may pass for disabled in one county comes no where near in another.

As I said, I suspect the assessor assumed that since this lady just qualified for free bus pass because of her age, she should not need blue badge. She does drive. She does have a car. But this is not much use to her, if she cannot make the walk from regular parking place to her destination.
