You got it....with Hurricane Katrina there was "supposedly" a legit reason gas prices jump almost $1 a gallon to $3.25+ a gallon...then demand did not slow and the gas companies saw this....so when the pipelines and supply lines where brought back up from the Katrina damage they knew they could keep prices up that high, now I think its just a game to see how high they can go before getting hurt. Just like everything else, it will top out and the bottom will blow out because by raising the gas prices so high...its now giving lots of folks the funding and economics to develop more efficient means of powering things.The real reason is no conspiracy, it's simple economics. Oil companies are businesses and there is a *sweet spot* for pricing things that gives you the most profit. Price something too high, demand decreases to a point where you make less money than if you charged less, price too low and demand doesn't cover the costs of production.
BTW...anyone catch the show "PassTime" on Speed last night...there was an electric powered dragster, ran on 492 NiCad batteries...ran a 8.62 at 139mph and was smoking the slicks on the start...never thought an electric car could do that.
