Diplomatic immunity, limos, etc. no tax. Wealthy are happy enough with it and the roads are that much emptier for them. So its a tax on ordinary citizens?
Question is why would an ordinary citizen want to be in central London which is not an ordinary place. Either as they expect to earn more money than everyone else, or they are being nosy as a tourist. Not greatly sympathetic then. Put a fence round it with gates like Berlin, I say. As a wild choice we can have Winchester as capitol of Wessex and London can knob off. Save me £50 a year on my council tax for a start. It can have its commuters back in trade for some piece and quiet and a lower standard of living round here, willingly.
I see several G Whizz round here. They are a collection of stuffed ones that the guy was looking to rebuild I think. He thought they would hold an enhanced value bit like Smarts did for a while. I assume they have not or he just has not got into rebuilding a few cars out of the wrecks.
Slightly worrying to see so many dead ones as they must be getting into situations where they are in accidents. They also do not look very robust.
