First few facts we must know :
NGV production now is more than demand(petrol is demand more than production)
NGV now only produce by Petronas, other companies like Shell and ESSO don't produce
Who own Petronas?
What if NGV demand is higher than production?
Like Daniel said, have to wait for long time then only can get, futhermore only on selected petrol station. I have seen where 30 taxies in a straight line waiting for NGV, if you are the 30th driver and NGV just finished.....
Who can ensure that NGV price will not increase for the next 5-10years? Is it you or me? As this is a rough calculation based on a day = 10-20km usage. The conversion is around rm3k.
This is just my point of view, not to condamn anyone, if the conversion is only 200-300, govermnet can assure us that the price will not go up for the next 5-10years then it will become another story.
