I don't often travel into the city centre, so you can imagine my surprise to find this in the middle of Central station.

Sure, i understand that it's difficult to find a park in the city, but i dunno that parking on the railway station concourse is the answer ;)
Mind you, i have sometimes wondered if parking lots could make slightly smaller parking spaces available - preferably at the most convenient places. Apart from creating more spaces, it would also reward drivers of smaller, less polluting vehicles.
