Lol - please don't tell me you believe this!
Cars do no "real" damage to the earth when you compare it to coal fired power plants, industry and commercial buildings.
The output of all the cars in this country wouldn't put a dent in teh output of the coal powered power palnts of China for example.
VED is set on CO2 output of the car no matter if you do 1 mile or 1 million miles. It is a fairly retarded system but relatively fair as none of them are that expensive - most people spend more on their monthly phone bill than you do on the HIGHEST VED band.
Then you pay further tax per mile you drive in the fuel you use. The more you drive the more you pay.
I dont know what to believe....
Like I said this is what those in power lead us to believe.... That in itself is another subject!
Is Global Warming caused by Humans?
