So long as the councils attitudes to streets is that they carparks and sources of revenue-generation, rather than places were people live, play and shock! horror! drive, cycle and walk then this sort of situation will never change.
The nicest thing about looking at old photos of Edinburgh is that you can see the streets and the pavements and the buildings without the sight of row upon rows of dull, mass-manufactured white-goods cars. Oh, and according to the comments it is the fault of cyclists and congestion and parking trouble never existed "before" (funnily enough, I was looking at the Domesday Revisited site earlier and the picture for Queensferry Road was "Morning traffic in the rain"!)
P.S. fascinating site, check it oot.
