I am all for artistic expression and the exuberance of youth. Let them loose in grey, soulless suburbs with cans of spray paint and grand designs for massive colourful murals, I say. While they are at it they won't have time to burn cars (with the exception of Micras, they are always welcome to decommission weapons of mass destruction like Micras or Yarises).
Let them be loud, and vibrant, and bold.
But the Dart... For fuck sake. The Dart! Is nothing sacred anymore?
