Malaysia petroleum subsidies - rationalization reasons?

According to to Dato Ahmad Maslan at Parliament today said subsidies rationalization  recently to decrease the amount of subsidies given to people earning more than RM 3,000/month. No substantial evidence to prove this.

Yes. Bigger car use more fuel than small size car or motorcycle but where is the fact to support it?

Questions:

1. How many people earning RM 3,000/month use car (big car & small size) & motorcycle?
2. How many people use credit card or cash to purchase fuel at petrol station?
3. What is their daily habit (behavior) of customer - individual and business?
4. How much subsidies per petrol station ? where is the hot spot? 

Recommendation:

1. Open data matter! With data from petrol station, we can visualize the energy flow in the country.
2. With data, we can engage stakeholders with much better decision.
