Petrol Pricing Breakthrough

I have had a brainstorm. How do you get people to pay a fair amount for fuel? Some people just have cars that are too large and it seems unfair that they pay the same amount for their petrol. I have a solution.

People should pay different amounts depending on their usage style.

Cautious drivers - 60 cents per litre
Moderate drivers - 80 cents per litre
Hoons, idiots, yobbos - $1.50 per litre

And lastly....

Holden drivers - at least $3.00 per litre (might get a few of them off the road).
