It's all about maintaining and reinforcing a class structure(based on money not necessarily social. charge everyone the same but those with lots of money wont care overmuch because they will add it to the purchase price of goods in whatever business they own,run or have shares in.it's also handy if you can afford an accountant to offset it somewhere along the way. this will be passed down the line to those of us who wouldn't be able to afford all this extra tax in the first place and make no mistake they wont reduce sod all!
As a driver of one of these TERRIBLE 4x4's I would also ask the people who are very busy condeming 4x4's to think about the future. The future when there are no 4x4's. The future when after a power cut in the middle of winter brings down power lines ( funnily enough the electricity supply people use 4x4's to get to places where the lines are down). The future where, after a natural disaster, the Smart car isn't able to bring aid. The future where the roads are clogged by idiots driving at 80 mph in the fast lane of a motorway with his mobile stuck to ther ears. The future where MP's are still being driven in Jaguars. The future where 2 lorries block roads whilst one passes the other using an extra 1mph to do it.The future where no one has any personal choice. Sorry the last 2 sentences are now!!
