what noone has mentioned and i think is a prevalent point here is that no matter how much more oil we get or what the price of that oil is is that now that the oil companys who produce the ever more precious gas for your car know that americans are willing to pay out the ass for that gas you will never see a significant reduction in the price at the pump.
it common sense in buisness you sell at the absolute highest price possible to the consummer at take in maximum profits.and if that number is $4.50 - $5.00 a galon for gas before the average person starts to signifacantly curb their usage then expect it to stay at that price.
and speaking of usage my boss told me couple weeks a go that average americans only spend 2% of their salary on gas. after i got up off the floor laughing i asked him what decade he was livin in. on my salary that would be me buyin 3 maybe 4 galons a week
