I'm inclined to agree with GabsAlot
Unrestricted parking spaces on the public highway are there for anybody to use on a first-come-first-served basis and do not belong to any single house.
HOWEVER, by having a drive, you have effectively gained the right to replace what could otherwise have been another available space for anybody to use with permanent access to your own property. It's only not a space for everybody to use because you have a drive which you want to access. In fact, if there are no yellow lines or white H-mark, you can usually get away with parking there yourself and 'blocking in' your own household, ergo you have scored the right to your own personal exclusive parking space on the public highway, which is not owned by you but which can only realistically be used by you, purely because you have a drive which you don't use anyway.
As a householder with a drive, I think that, if it can be proved that a householder is never using their drive for a vehicle(s) and instead choosing to occupy one or more general spaces on the public road which could otherwise be used by those without their own special drive-access concessions, they should lose the right to their unused drive-access privilege and it be marked out as a normal parking space and specifically labelled as free to all.
Also with the council disabled bays, it should be the standard terms that, on selling/vacating the property, the blue badge holding resident must notify the council, who will then come and scrub out the space - unless the new resident is also a blue badge holder or there can otherwise be shown to be a genuine need for frequent disabled visitors to use it.
Most of the houses on the other side of the road to ours don't have drives, so the road parking is at a real premium. There were two next-door neighbours with blue badges who had requested disabled spaces and the council took so long to do it that, two weeks after they'd painted the spaces, one of the disabled residents had moved out. Sensibly (at last), the council came and scrubbed out one of the two new spaces. If they hadn't, it would just have gone unused with the space being badly needed by non-disabled residents.
