About proton : Need to partner with others to survive and develop. Malaysia is too small to fund the it. Suck money in instead of circulate within country/leak out of the country.
About gov : why heavy tax then subsidise petrol? Like put money inside gov pocket (for invest/earn interest) then only vomit back to buyer through pertrol subsidy. Those who travel less, get less. Also safety features are compromised.
About currency : US/china has less impact as they can survive without import, their agriculture/food supply is strong enough to supply their own. Malaysia now seems neither importer nor exporter, rice/vegetables/or even fish import from asean countries. The best exporting goods are still palm oil/petrol (which direct beneficial to cooperation/stake holders). Now vietnam coming up with "cheaper labour". So need to further devalue the currency for "cheaper labour"? There left only 7y to 2020.. lets see how the curreny and "transformasi" work out.
