We naturally feel paying double or triple for our cars is unfair. But we have to look at the issue in the right perspective.
Firstly, to recover the lost tax revenue through higher income taxes would be unfair to those who don't own cars and use public transport instead.
And then, it may be cheaper to buy a car say in Europe, but their petrol is taxed at something like 75%, and are generally above 1 Euro per liter now.
http://www.karzoo.eu/en/calculators/petrol-prices At today's rate of E1.00 = RM4.93, Brits pay RM5.75 per liter, Germans RM6.40 and Norwegians RM6.85
for 95 octane. That's more than triple our petrol price, which most of the time, is subsidised rather than taxed. Norway is an oil producing country too, BTW.
Would we rather have cars costing 1/3 and petrol costing 3x? Then our 1.5 million new vehicles per annum would go up to 2 million per annum or more. No point having a car then, because it would be too expensive to pump petrol (a full tank would cost RM300+), the streets would be eternallly jammed, and when you get to your destination there would be no place to park because there would be 20 million vehicles in the country.
Our government policies on car and petrol prices don't look so bad when you look at things in perspective. The only gripe I have about the current duty regime is that non-national car owners are subsidising national car owners. But then, nobody is forcing me to buy a non-national...
