Whatever. That damn bell curve doesn’t seem to be accurate any more.
The price of oil has dropped significantly but, our gas price has stayed the same.
On the way up, the oil price was increasing without gas prices going up as much, so it's not not surprising. Even when gas prices rose, the oil prices had risen faster--tripling in price, from about $50 to $150/barrel, while gasoline did not jump from $2 to $6/gallon.
So when the price of oil came down, why would we expect the price to drop proportionately?
