There needs to be less rules and more common sense.
If a supermarket sees all it's disabled spaces are used it should paint more.
If they or the local council parking wardens find ones that are never used they should paint less.
The ones that annoy me are in a multi storey with a lift my long Mountain buggy didn't fit. No room for an adult wheelchair and a carer.
More disabled spaces on the ground floor, or in the accessible carpark nearer the shops (where they were always full) would have made so much more sense.
