It's to try and encourage people to drive more economical cars that emit less CO2.
I know, I was being flippant :winky:
What I object to is the premise of paying zero raod tax, when a prius does similiar damage to the roads than any other car. It's just me being pedantic about the vanacular used, our "road tax" should be in proportion to the charges levied against road maintenance. By all means have a "green tax" .....but that would mean transparency, something our present government aren't really into!
Even in a situation such as a the above, the prius still puts out 104 g/km doesn't it?(not to mention the crazy ammount of c02 that goes into making the thing!) I know thats F all, but still, for you to be paying ZERO road tax I'd expect a fully electric car putting out ZERO c02 emissions. (but then, when does your electricity come from...it's hardly innocent of c02 is it!)
I'm not having a go! I too have considered ditching the lex (it was a fleeting thought!) but I'm far to stubborn to bend over for brown thank you!
