Revenons à nos moutons ...
The real answer is to shut all the piddling little facilities in the centres of urban areas and build "feck me that's big" medical centres in the back of beyond - with car parks the size of Watford and shuttle buses from the surrounding towns.
It's efficient, it's cheap, parking is free, the blue lights can get there quickly and it cuts down the 'frequent flier' idiots at A&E too ... but ... but ... but ...
... if you suggest this you will face united opposition from every dog and his frog. The tree huggers will condemn you, the 'local hospitals for local people' crew will condemn you (however much you wave the poor outcome results of the existing Victorian Nightmare at them) and the staff will hate you because they can't go shopping in their lunch hour.
So don't bother even suggesting a proper solution - just campaign for the heirs of Florence Nightingale to get free parking and we'll all be fine ... or not.
