its all quite logical really
put a tax on cars making the higher polluting ones cost more to tax
therefore the car buyer thinks twice and actually looks at what pollution his/her car produces and makes the decision to get a lower polluting car
the result is less pollution
the manufacturers then notice that they have trouble selling high polluting cars, they then start producing lower polluting cars
(compare 2004 yaris to 2009 yaris to see this is working)
overall the effect is lower pollution levels, which can only be good
you only have to look at this thread and you will see the proof of it all working
"well i have just bought one years road tax for £215 and if the road tax price is going up then i am going to get rid of my car by the summer and move onto my next car"
I am pretty sure that the next car will be a lower tax band !
why raise tax ?
because it directly affects the drivers pocket, how else would they make the impact they require !
the more everyone moans, the more successful it makes the whole scheme
simple :D
