These various systems to help are very well hidden.
My similar aged mate i knew when we were both 5, had his benefit, which involved a motability car removed. He had a motorcycle accident in 1981 losing a right leg and the use of his right arm.
They took the car back during his appeal and sold it off.
I told him to go into the tribunal in his wheelchair and no leg and demonstrate how at 64, he could hop on one leg to do his shopping.
When he entered the tribunal, the Doctor said no one had ever grown a new leg and awarded it all back. He then had to collect another new car. Its a weird World if you ask for help
