The emerging economies of China and India are largely responsible for the current price of oil.  China is second only to the US in terms of oil consumption.  You are correct that the weak US dollar has contributed to the spike in oil prices worldwide, but the $9.00 to $10.00 per gallon figure you cite is mostly taxes.

I don't know how closely you've been following it, but the price of oil is on the way down and many speculators are now bearish on the oil market.  Speculation ensures future price stability and the current system does work, as evidenced by the fact that gasoline is still available.  I suppose you would rather go back to the failed policies of price controls and onerous taxes of the 1970s which resulted in shortages, rationing and long lines at the gas pumps.  More regulation will only result in higher prices and scarcity of resources.
