we could easily cut our oil dependecy in half if the poeple with money aka the oil companies didn't control the car/ energy market, and wheren't making so much money in those markets, the funny thing about the the prius and other new cars isthey get around 40mpg, in the late 70's and early 80's vw was making rabits with deasil engines that got 50 mpg, convert that to biodeasel and you now have a vehicle that polutes less and goes farther, ie is more effient and in the early 80's honda accords and other such cars where getting 35+ mpg, now days people are happy to get 20 + mpg its stupid and the reason are pretty obious. its quite ironic that since the war in iraq started gas prices have nearly doubled, yeah we didn't go there to get oil, we went there to close that market and thereby drive prices up, so the people here that owned oil got more money for it.
